From ccb29637991fa6b8321a80c2320a71e379aea962 Mon Sep 17 00:00:00 2001 From: Oliver Hartkopp Date: Fri, 16 Nov 2007 15:56:08 -0800 Subject: [CAN]: Add virtual CAN netdevice driver This patch adds the virtual CAN bus (vcan) network driver. The vcan device is just a loopback device for CAN frames, no real CAN hardware is involved. Signed-off-by: Oliver Hartkopp Signed-off-by: Urs Thuermann Signed-off-by: David S.

It slightly modifies the tg3_setup_fiber_mii_phy() function to account for this new use case. And finally, it does the same for tg3_setup_copper_phy(). The copper modifications are more than a small multi-line change. The new code makes an attempt to avoid a link renegotiation if the link is active at half duplex and the only difference between the current advertised settings and requested advertised settings is the flow control advertisements.

This also implies that rt2x00 should no longer write the hw->config.antenna_sel_* values based on the EEPROM input. This also adds the basis in rt2x00lib for correct software diversity handling.

This patch changes rt61 antenna selection again. It helps at least with the rt61 pci card in my box, I hope I haven't broken behaviour on other RF chips. RF 2529 antenna setup is incomplete, we need to at code for diversity when we figure out how it is done properly. Signed-off-by: Mattias Nissler Signed-off-by: Ivo van Doorn Signed-off-by: John W.

There is also the possibility if multiple threads try to access BBP or RF registers for the multiple USB operations needed to get interleaved leading to incorrect results. This patch introduces a mutex to prevent such simultaneous access. The interleaved access problem may also affect the PCI devices but if so that will be handled in a follow-up patch.

This split it up into options for the individual drivers and gets rid of all the CONFIG_IWLWIFI cruft. Signed-off-by: Christoph Hellwig Signed-off-by: Zhu Yi Signed-off-by: John W.

This patch restores the PHY-specific code. This is mostly uninteresting since no copper PHY boards are yet available. The changes have been tested against Fiber only as I do not even have copper PHY versions of 82598 macs. This change actually cleans up the API code a bit more and we lose some initialization code. A few PHY link detection helper lines of code have been snuck into this patch, as well as a read flush where it was suspected that this might cause issues.

The two race on touching the last Receive Frame Descriptor (RFD). It has its el-bit set and its next link equal to 0. When hardware encounters this buffer it attempts to write data to it and then update Status Word bits and Actual Count in the RFD. At the same time software may try to clear the el-bit and set the link address to a new buffer. Since the entire RFD is once cache-line, the two write operations can collide. This can lead to the receive unit stalling or interpreting random memory as its receive area. The fix is to set the el-bit on and the size to 0 on the next to last buffer in the chain. When the hardware encounters this buffer it stops and does not write to it at all. The hardware issues an RNR interrupt with the receive unit in the No Resources state. Software can write to the tail of the list because it knows hardware will stop on the previous descriptor that was marked as the end of list. Once it has a new next to last buffer prepared, it can clear the el-bit and set the size on the previous one. The race on this buffer is safe since the link already points to a valid next buffer and the software can handle the race setting the size (assuming aligned 16 bit writes are atomic with respect to the DMA read). If the hardware sees the el-bit cleared without the size set, it will move on to the next buffer and skip this one. If it sees the size set but the el-bit still set, it will complete that buffer and then RNR interrupt and wait.

We don't have a timer-delayed interrupt on TX complete, but we have a count threshold. So set that reasonably high (32 packets), and schedule the NAPI poll when it goes off. Also bump a regular timer that will take care of rotting packets for the last 1..31 ones in case we don't trigger a TX interrupt (and there's no RX activity that would otherwise trigger the poll). The longer-term fix is to separate TX from RX NAPI and do two separate poll loops.

This is less than optimal, especially for LRO where it's better if we have a more substantial amount of packets to process at once, to get the real LRO benefits. So, set the count threshold to a higher value and use the timeout feature that will give us an interrupt even if not enough packets have come in to set off the count threshold.

They used to return 0, which means we can switch to HT rate causing the rate scale problem and the error message. The patch also fix another bug reported by Ben Cahill that it uses wrong value for max_success_limit.

For this: * it tells cmd.c and cmdresp.c about CMD_802_11_SUBSCRIBE_EVENT * removes lots of low-level cmd stuff from debugfs.c * create unified functions to read/write snr, rssi, bcnmiss and failcount * introduces #define's for subscription event bitmask values * add a function to search for a specific element in an IE (a.k.a. TLV) * add a function to find out the size of the TLV.

The changes include the following: (1) Add the 802.11 rev 13 device to the ssb_device_id table to load b43. (2) Add PHY revision 9 to the supported list. (3) Change the 2-bit routing code for address extensions to 0b10 rather than the 0b01 used for the 32-bit case. (4) Remove some magic numbers in the DMA setup. The DMA implementation for this chip supports full 64-bit addressing with one exception. Whenever the Descriptor Ring Buffer is in high memory, a fatal DMA error occurs. This problem was not present in 2.6.24-rc2 due to code to "Bias the placement of kernel pages at lower PFNs". When commit 44048d70 reverted that code, the DMA error appeared. As a "fix", use the GFP_DMA flag when allocating the buffer for 64-bit DMA. At present, this problem is thought to arise from a hardware error.

The intention is that with this approach debugging of rt2x00 is simplified since _all_ frames going in and out of the device are send to debugfs as well along with additional information like the hardware descriptor. Based on the patch by Mattias Nissler.

The rest of + * the steps figure out the proper settings for the device to achieve + * that target txpower. + * + * + * 3) Determine (EEPROM) calibration subband for the target channel, by + * comparing against first and last channels in each subband + * (see struct iwl4965_eeprom_calib_subband_info). + * + * + * 4) Linearly interpolate (EEPROM) factory calibration measurement sets, + * referencing the 2 factory-measured (sample) channels within the subband. + * + * Interpolation is based on difference between target channel's frequency + * and the sample channels' frequencies. Since channel numbers are based + * on frequency (5 MHz between each channel number), this is equivalent + * to interpolating based on channel number differences. + * + * Note that the sample channels may or may not be the channels at the + * edges of the subband. The target channel may be "outside" of the + * span of the sampled channels. + * + * Driver may choose the pair (for 2 Tx chains) of measurements (see + * struct iwl4965_eeprom_calib_ch_info) for which the actual measured + * txpower comes closest to the desired txpower. Usually, though, + * the middle set of measurements is closest to the regulatory limits, + * and is therefore a good choice for all txpower calculations (this + * assumes that high accuracy is needed for maximizing legal txpower, + * while lower txpower configurations do not need as much accuracy). + * + * Driver should interpolate both members of the chosen measurement pair, + * i.e. for both Tx chains (radio transmitters), unless the driver knows + * that only one of the chains will be used (e.g. only one tx antenna + * connected, but this should be unusual). The rate scaling algorithm + * switches antennas to find best performance, so both Tx chains will + * be used (although only one at a time) even for non-MIMO transmissions. + * + * Driver should interpolate factory values for temperature, gain table + * index, and actual power. The power amplifier detector values are + * not used by the driver. + * + * Sanity check: If the target channel happens to be one of the sample + * channels, the results should agree with the sample channel's + * measurements! + * + * + * 5) Find difference between desired txpower and (interpolated) + * factory-measured txpower. Using (interpolated) factory gain table index + * (shown elsewhere) as a starting point, adjust this index lower to + * increase txpower, or higher to decrease txpower, until the target + * txpower is reached. Each step in the gain table is 1/2 dB. + * + * For example, if factory measured txpower is 16 dBm, and target txpower + * is 13 dBm, add 6 steps to the factory gain index to reduce txpower + * by 3 dB. + * + * + * 6) Find difference between current device temperature and (interpolated) + * factory-measured temperature for sub-band. Factory values are in + * degrees Celsius. To calculate current temperature, see comments for + * "4965 temperature calculation". + * + * If current temperature is higher than factory temperature, driver must + * increase gain (lower gain table index), and vice versa. + * + * Temperature affects gain differently for different channels: + * + * 2.4 GHz all channels: 3.5 degrees per half-dB step + * 5 GHz channels 34-43: 4.5 degrees per half-dB step + * 5 GHz channels >= 44: 4.0 degrees per half-dB step + * + * NOTE: Temperature can increase rapidly when transmitting, especially + * with heavy traffic at high txpowers. Driver should update + * temperature calculations often under these conditions to + * maintain strong txpower in the face of rising temperature. + * + * + * 7) Find difference between current power supply voltage indicator + * (from "initialize alive") and factory-measured power supply voltage + * indicator (EEPROM). + * + * If the current voltage is higher (indicator is lower) than factory + * voltage, gain should be reduced (gain table index increased) by: + * + * (eeprom - current) / 7 + * + * If the current voltage is lower (indicator is higher) than factory + * voltage, gain should be increased (gain table index decreased) by: + * + * 2 * (current - eeprom) / 7 + * + * If number of index steps in either direction turns out to be > 2, + * something is wrong ... just use 0. + * + * NOTE: Voltage compensation is independent of band/channel. + * + * NOTE: "Initialize" uCode measures current voltage, which is assumed + * to be constant after this initial measurement. Voltage + * compensation for txpower (number of steps in gain table) + * may be calculated once and used until the next uCode bootload. + * + * + * 8) If setting up txpowers for MIMO rates (rate indexes 8-15, 24-31), + * adjust txpower for each transmitter chain, so txpower is balanced + * between the two chains. There are 5 pairs of tx_atten[group][chain] + * values in "initialize alive", one pair for each of 5 channel ranges: + * + * Group 0: 5 GHz channel 34-43 + * Group 1: 5 GHz channel 44-70 + * Group 2: 5 GHz channel 71-124 + * Group 3: 5 GHz channel 125-200 + * Group 4: 2.4 GHz all channels + * + * Add the tx_atten[group][chain] value to the index for the target chain. + * The values are signed, but are in pairs of 0 and a non-negative number, + * so as to reduce gain (if necessary) of the "hotter" channel.

The device + * automatically processes block-acks received from the receiving STA, + * and reschedules un-acked frames to be retransmitted (successful + * Tx completion may end up being out-of-order). + * + * The driver must maintain the queue's Byte Count table in host DRAM + * (struct iwl4965_sched_queue_byte_cnt_tbl) for this mode. + * This mode does not support fragmentation. + * + * 2) FIFO (a.k.a. non-Scheduler-ACK), in which each TFD is processed in order. + * The device may automatically retry Tx, but will retry only one frame + * at a time, until receiving ACK from receiving station, or reaching + * retry limit and giving up. + * + * The command queue (#4) must use this mode! + * This mode does not require use of the Byte Count table in host DRAM. + * + * Driver controls scheduler operation via 3 means: + * 1) Scheduler registers + * 2) Shared scheduler data base in internal 4956 SRAM + * 3) Shared data in host DRAM + * + * Initialization: + * + * When loading, driver should allocate memory for: + * 1) 16 TFD circular buffers, each with space for (typically) 256 TFDs. + * 2) 16 Byte Count circular buffers in 16 KBytes contiguous memory + * (1024 bytes for each queue). + * + * After receiving "Alive" response from uCode, driver must initialize + * the scheduler (especially for queue #4, the command queue, otherwise + * the driver can't issue commands!): + */ + +/** + * Max Tx window size is the max number of contiguous TFDs that the scheduler + * can keep track of at one time when creating block-ack chains of frames. + * Note that "64" matches the number of ack bits in a block-ack packet. + * Driver should use SCD_WIN_SIZE and SCD_FRAME_LIMIT values to initialize + * SCD_CONTEXT_QUEUE_OFFSET(x) values. + */ #define SCD_WIN_SIZE 64 #define SCD_FRAME_LIMIT 64 -/* SRAM structures */ -#define SCD_CONTEXT_DATA_OFFSET 0x380 -#define SCD_TX_STTS_BITMAP_OFFSET 0x400 -#define SCD_TRANSLATE_TBL_OFFSET 0x500 -#define SCD_CONTEXT_QUEUE_OFFSET(x) (SCD_CONTEXT_DATA_OFFSET + ((x) * 8)) -#define SCD_TRANSLATE_TBL_OFFSET_QUEUE(x) \ - ((SCD_TRANSLATE_TBL_OFFSET + ((x) * 2)) & 0xfffffffc) +/* SCD registers are internal, must be accessed via HBUS_TARG_PRPH regs */ +#define SCD_START_OFFSET 0xa02c00 + +/* + * 4965 tells driver SRAM address for internal scheduler structs via this reg. + * Value is valid only after "Alive" response from uCode. + */ +#define SCD_SRAM_BASE_ADDR (SCD_START_OFFSET + 0x0) +/* + * Driver may need to update queue-empty bits after changing queue's + * write and read pointers (indexes) during (re-)initialization (i.e. when + * scheduler is not tracking what's happening). + * Bit fields: + * 31-16: Write mask -- 1: update empty bit, 0: don't change empty bit + * 15-00: Empty state, one for each queue -- 1: empty, 0: non-empty + * NOTE: This register is not used by Linux driver. + */ +#define SCD_EMPTY_BITS (SCD_START_OFFSET + 0x4) + +/* + * Physical base address of array of byte count (BC) circular buffers (CBs). + * Each Tx queue has a BC CB in host DRAM to support Scheduler-ACK mode. + * This register points to BC CB for queue 0, must be on 1024-byte boundary. + * Others are spaced by 1024 bytes. + * Each BC CB is 2 bytes * (256 + 64) = 740 bytes, followed by 384 bytes pad. + * (Index into a queue's BC CB) = (index into queue's TFD CB) = (SSN & 0xff). + * Bit fields: + * 25-00: Byte Count CB physical address [35:10], must be 1024-byte aligned. + */ +#define SCD_DRAM_BASE_ADDR (SCD_START_OFFSET + 0x10) + +/* + * Enables any/all Tx DMA/FIFO channels. + * Scheduler generates requests for only the active channels. + * Set this to 0xff to enable all 8 channels (normal usage). + * Bit fields: + * 7- 0: Enable (1), disable (0), one bit for each channel 0-7 + */ +#define SCD_TXFACT (SCD_START_OFFSET + 0x1c) + +/* Mask to enable contiguous Tx DMA/FIFO channels between "lo" and "hi". */ #define SCD_TXFACT_REG_TXFIFO_MASK(lo, hi) \ ((1<<(hi))|((1<<(hi))-(1<<(lo)))) +/* + * Queue (x) Write Pointers (indexes, really!), one for each Tx queue. + * Initialized and updated by driver as new TFDs are added to queue. + * NOTE: If using Block Ack, index must correspond to frame's + * Start Sequence Number; index = (SSN & 0xff) + * NOTE: Alternative to HBUS_TARG_WRPTR, which is what Linux driver uses?

If no lower rate available, switch to + * legacy mode (no FAT channel, no MIMO, no short guard interval). + * c) If using MIMO, set command's mimo_delimiter to number of entries + * using MIMO (3 or 6). + * d) After trying 2 HT rates, switch to legacy mode (no FAT channel, + * no MIMO, no short guard interval), at the next lower bit rate + * (e.g. if second HT bit rate was 54, try 48 legacy), and follow + * legacy procedure for remaining table entries. + * + * 2) If using legacy initial rate: + * a) Use the initial rate for only one entry. + * b) For each following entry, reduce the rate to next lower available + * rate, until reaching the lowest available rate. + * c) When reducing rate, also switch antenna selection. + * d) Once lowest available rate is reached, repeat this rate until + * rate table is filled (16 entries), switching antenna each entry. + * + * + * ACCUMULATING HISTORY + * + * The rate scaling algorithm for 4965, as implemented in Linux driver, uses + * two sets of frame Tx success history: One for the current/active modulation + * mode, and one for a speculative/search mode that is being attempted. If the + * speculative mode turns out to be more effective (i.e. actual transfer + * rate is better), then the driver continues to use the speculative mode + * as the new current active mode. + * + * Each history set contains, separately for each possible rate, data for a + * sliding window of the 62 most recent tx attempts at that rate. The data + * includes a shifting bitmap of success(1)/failure(0), and sums of successful + * and attempted frames, from which the driver can additionally calculate a + * success ratio (success / attempted) and number of failures + * (attempted - success), and control the size of the window (attempted). + * The driver uses the bit map to remove successes from the success sum, as + * the oldest tx attempts fall out of the window. + * + * When the 4965 makes multiple tx attempts for a given frame, each attempt + * might be at a different rate, and have different modulation characteristics + * (e.g. antenna, fat channel, short guard interval), as set up in the rate + * scaling table in the Link Quality command. The driver must determine + * which rate table entry was used for each tx attempt, to determine which + * rate-specific history to update, and record only those attempts that + * match the modulation characteristics of the history set. + * + * When using block-ack (aggregation), all frames are transmitted at the same + * rate, since there is no per-attempt acknowledgement from the destination + * station. The Tx response struct iwl_tx_resp indicates the Tx rate in + * rate_n_flags field. After receiving a block-ack, the driver can update + * history for the entire block all at once. + * + * + * FINDING BEST STARTING RATE: + * + * When working with a selected initial modulation mode (see below), the + * driver attempts to find a best initial rate. The initial rate is the + * first entry in the Link Quality command's rate table. + * + * 1) Calculate actual throughput (success ratio * expected throughput, see + * table below) for current initial rate. Do this only if enough frames + * have been attempted to make the value meaningful: at least 6 failed + * tx attempts, or at least 8 successes. If not enough, don't try rate + * scaling yet. + * + * 2) Find available rates adjacent to current initial rate. Available means: + * a) supported by hardware && + * b) supported by association && + * c) within any constraints selected by user + * + * 3) Gather measured throughputs for adjacent rates. These might not have + * enough history to calculate a throughput. That's okay, we might try + * using one of them anyway! + * + * 4) Try decreasing rate if, for current rate: + * a) success ratio is < 15% || + * b) lower adjacent rate has better measured throughput || + * c) higher adjacent rate has worse throughput, and lower is unmeasured + * + * As a sanity check, if decrease was determined above, leave rate + * unchanged if: + * a) lower rate unavailable + * b) success ratio at current rate > 85% (very good) + * c) current measured throughput is better than expected throughput + * of lower rate (under perfect 100% tx conditions, see table below) + * + * 5) Try increasing rate if, for current rate: + * a) success ratio is < 15% || + * b) both adjacent rates' throughputs are unmeasured (try it!) || + * b) higher adjacent rate has better measured throughput || + * c) lower adjacent rate has worse throughput, and higher is unmeasured + * + * As a sanity check, if increase was determined above, leave rate + * unchanged if: + * a) success ratio at current rate < 70%. This is not particularly + * good performance; higher rate is sure to have poorer success. + * + * 6) Re-evaluate the rate after each tx frame. If working with block- + * acknowledge, history and statistics may be calculated for the entire + * block (including prior history that fits within the history windows), + * before re-evaluation. + * + * FINDING BEST STARTING MODULATION MODE: + * + * After working with a modulation mode for a "while" (and doing rate scaling), + * the driver searches for a new initial mode in an attempt to improve + * throughput. The "while" is measured by numbers of attempted frames: + * + * For legacy mode, search for new mode after: + * 480 successful frames, or 160 failed frames + * For high-throughput modes (SISO or MIMO), search for new mode after: + * 4500 successful frames, or 400 failed frames + * + * Mode switch possibilities are (3 for each mode): + * + * For legacy: + * Change antenna, try SISO (if HT association), try MIMO (if HT association) + * For SISO: + * Change antenna, try MIMO, try shortened guard interval (SGI) + * For MIMO: + * Try SISO antenna A, SISO antenna B, try shortened guard interval (SGI) + * + * When trying a new mode, use the same bit rate as the old/current mode when + * trying antenna switches and shortened guard interval. When switching to + * SISO from MIMO or legacy, or to MIMO from SISO or legacy, use a rate + * for which the expected throughput (under perfect conditions) is about the + * same or slightly better than the actual measured throughput delivered by + * the old/current mode. + * + * Actual throughput can be estimated by multiplying the expected throughput + * by the success ratio (successful / attempted tx frames). Frame size is + * not considered in this calculation; it assumes that frame size will average + * out to be fairly consistent over several samples. The following are + * metric values for expected throughput assuming 100% success ratio. + * Only G band has support for CCK rates: + * + * RATE: 1 2 5 11 6 9 12 18 24 36 48 54 60 + * + * G: 7 13 35 58 40 57 72 98 121 154 177 186 186 + * A: 0 0 0 0 40 57 72 98 121 154 177 186 186 + * SISO 20MHz: 0 0 0 0 42 42 76 102 124 159 183 193 202 + * SGI SISO 20MHz: 0 0 0 0 46 46 82 110 132 168 192 202 211 + * MIMO 20MHz: 0 0 0 0 74 74 123 155 179 214 236 244 251 + * SGI MIMO 20MHz: 0 0 0 0 81 81 131 164 188 222 243 251 257 + * SISO 40MHz: 0 0 0 0 77 77 127 160 184 220 242 250 257 + * SGI SISO 40MHz: 0 0 0 0 83 83 135 169 193 229 250 257 264 + * MIMO 40MHz: 0 0 0 0 123 123 182 214 235 264 279 285 289 + * SGI MIMO 40MHz: 0 0 0 0 131 131 191 222 242 270 284 289 293 + * + * After the new mode has been tried for a short while (minimum of 6 failed + * frames or 8 successful frames), compare success ratio and actual throughput + * estimate of the new mode with the old.

Now the driver will print an error if it is unable to register the sysfs files. It also eliminates the macros used to wrap the DEVICE_ATTR macro and the device_create_file function call. The macros don't reduce the number of lines of source code in the file and the name munging makes is so that cscope and friends don't see the references to the functions. It's better to just call the kernel API directly. While we're at it, the DEVICE_ATTR instances have been moved down to be grouped with the functions they depend on.

It incorrectly removed the writing of the high 16bits for a 32bit table write and initialized the direction identifier too late. This patch does also some cleanups to make the code much more readable and adds a few comments, so non rocket scientists are also able to understand what this address caching is all about.

Firstly, they set the frame type, which isn't necessary since lbs_hard_start_xmit() gets to see which device it belongs to anyway. Secondly, they return -EOPNOTSUPP if the device is in monitor mode. Which is a strange thing to do and will provide nasty warnings from qdisc_restart(). And lbs_hard_start_xmit() seems to have code to cope with monitor mode anyway.

Introduced when setup_hw_rings() went in, screwed both 64bit case and the old code for 32bit rings it had replaced.

Enable continuous tx interrupt when link is UP and vice verse. - Enable transmit interrupts for all configured transmit fifos. - Fixed typo errors.

This patch is the equivalent of one submitted earlier for b43. Since addition of the rfkill callback, the LED associated with the off switch on the radio has not worked for several reasons: (1) Essential data in the rfkill structure were missing. (2) The rfkill structure was initialized after the LED initialization. (3) There was a minor memory leak if the radio LED structure was inited. Once the above problems were fixed, additional difficulties were noted: (4) The radio LED was in the wrong state at startup. (5) The radio switch had to be manipulated twice for each state change. (6) A circular mutex locking situation existed. (7) If rfkill-input is built as a module, it is not automatically loaded. This patch fixes all of the above and removes a couple of sparse warnings.

NEWEMAC: Fix problem with mtu > 4080 on non TAH equipped 4xx PPC's Currently, all non TAH equipped 4xx PPC's call emac_start_xmit() upon xmit. This routine doesn't check if the frame length exceeds the max. MAL buffer size. This patch now changes the driver to call emac_start_xmit_sg() on all GigE platforms and not only the TAH equipped ones (440GX). This enables an MTU of 9000 instead 4080.

Somebody got too enthusiatic and replaced ntohs(p->mrx_overflow) with ntohs(read(&p->mrx_overflow) without noticing that (a) the sucker is 16bit and (b) that expression can't possibly be portable anyway (hell, on l-e it's always less than 256, on b-e it's always a multiple of 256). Proper fix is swab16(readw(&p->mrx_overflow) taking into account the conversion done by readw() itself. That crap happened in several places; the same fix applies. * untranslate() assumes little-endian almost everywhere, except for the code checking for IPX/AARP packets; there we forgot ntohs(), so that part only works on big-endian.

Subject: Add rtl8180 wireless driver This patch adds a mac80211 based wireless driver for the rtl8180 and rtl8185 PCI wireless cards. Also included are some rtl8187 changes required due to the relationship between that driver and this one. Michael Wu is primarily responsible for the initial driver and rtl8185 support. Andreas Merello provided the additional rtl8180 support. Thanks to Jukka Ruohonen for the donating a rtl8185 card! It was very helpful for the rtl8225z2 code. The Signed-off-by information below is collected from the individual patches submitted to wireless-2.6 before merging this driver upstream.

This structure is located at the end of the per-interface structure and contains a variable length driver-use data area. This has two advantages: * removes the need to look up interfaces by if_id, this is better for working with network namespaces and performance * allows drivers to store and retrieve per-interface data without having to allocate own lists/hash tables Signed-off-by: Johannes Berg Signed-off-by: John W.

Rodriguez" Date: Fri, 4 Jan 2008 02:21:05 -0500 Subject: ath5k: Fix frame duration oops This patch fixes an oops which was introduced as a regression by commit fd640775bd16e1df50c867cc547af0, on the patch titled, "mac80211: dont use interface indices in drivers". ieee80211_generic_frame_duration() now relies on sdata->flags which itself gets set upon bringing the interface up. We check for the virtual interface now before setting the rate duration registers. After the mode changes are introduced onto mac80211 we should revisit these changes. This patch was tested on the following cards: 1) BG card: Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43) RF2112A 2GHz radio found (0x46) 2) ABG card: Atheros AR5213A chip found (MAC: 0x59,PHY: 0x43) RF5112A multiband radio found (0x36) Signed-off-by: Luis R.

This patch introduces new ieee80211_bss_conf structure that is passed to the driver via the new bss_info_changed() callback when the BSS configuration changes. This new BSS configuration infrastructure adds the following new features: * drivers are notified of their association AID * drivers are notified of association status and replaces the erp_ie_changed() callback. The patch also does the relevant driver updates for the latter change. Signed-off-by: Ron Rindjunsky Signed-off-by: Johannes Berg Signed-off-by: John W.

Old firmware is still supported until July 2008. To get new firmware, go to ftp://ftp.linksys.com/opensourcecode/wrt150nv11/1.51.3/ and download the tarball. We don't have a smaller tarball, yet. That will be fixed later. You can extract firmware out of the "wl_ap.o" file contained in this tarball using latest fwcutter. You must pass the option --unsupported to fwcutter. Fwcutter-010 with official support for a new firmware image will be released soon. Signed-off-by: Michael Buesch Signed-off-by: John W. Linville Signed-off-by: David S.

There are two reasons for doing this: 1. To support kernel buildin iwlwifi drivers. Because kernel initializes network devices subsystem before hard disk and SATA subsystem, it is impossible to get the firmware image from hard disk in the PCI probe handler. Thus delaying the firmware loading into the network interface open time is the way to go. Note, we only read the firmware image from hard disk the first time the interface is open. After this is succeeded, we cache the firmware image into the host memory. This is a performance gain when user open and close the interface multiple times and is necessary for device suspend and resume. 2. For better power saving. When the iwlwifi modules are loaded (or buildin the kernel) but the wireless network interface is not being used, it is a good practice the wireless device consumes as less power as possible. Unloading the firmware from the wireless device and unregister the driver's interrupt handler in the network interface close handler provides users a way to achieve this. User space network configuration tools (i.e NetworkManager) can also contribute here when it detects a wired cable is connected and close the wireless interface automatically. This patch also includes the pci_save/restore_state() fixed by Ian Schram upon the first version. Signed-off-by: Zhu Yi Signed-off-by: Ian Schram Signed-off-by: John W.

For example, before suspend we can have interface up or down, rf_kill enable or disable; before resume we can have rf_kill enable or disable. So there are totally 2^3 = 8 conditions to handle. This patch addressed this problem and makes sure every condition works correctly. This patch also merges the device suspend and resume handlers with the mac_start and mac_stop code since they are basically doing the same thing. Signed-off-by: Zhu Yi Signed-off-by: John W.

This type represents a station's link quality. 2. The names of the variables of this type were rs_priv, lq_data, lq, crl across the file. All are now unified under the name lq_sta.

This product is the Intel(R) 82575 Gigabit Ethernet adapter family. Physical adapters will be available to the public soon. These adapters come in 2- and 4-port versions (copper PHY) currently. Other variants will be available later. The 82575 chipset supports significantly different features that warrant a new driver. The descriptor format is (just like the ixgbe driver) different. The device can use multiple MSI-X vectors and multiple queues for both send and receive. This allows us to optimize some of the driver code specifically as well compared to the e1000-supported devices. This version of the igb driver no lnger uses fake netdevices and incorporates napi_struct members for each ring to do the multi- queue polling. multi-queue is enabled by default and the driver supports NAPI mode only. All the namespace collisions should be gone in this version too. The register macro's have been condensed to improve readability.

+0100 Subject: b43: Fix firmware caching We must also store the ID string (filename) for the cached firmware blobs and verify that we really have the right firmware cached before using it. If we don't have the right fw cached, we must free it and request the correct blobs. This fixes bandswitch on A/B/G multi-PHY devices. Signed-off-by: Michael Buesch Signed-off-by: John W.

This also fixes initialization of the MAC control register. The _only_ place where we overwrite the contents of the MAC control register is at the beginning of b43_chip_init(). All other places must do read() -> mask/set -> write() to not overwrite existing bits. This also adds a longer delay for waiting for the microcode to initialize itself. It seems that the current timeout is sufficient on all available devices, but there's no real reason why we shouldn't wait for up to one second. Slow embedded devices might exist.
