2010-12-08ath: Fix ath_dbg access beyond array boundJoe Perches1-25/+2
ar9300RateSize is not necessarily a power of 4. Change ar9003_hw_set_target_power_eeprom to print the targetPowerValT2 array one per line. ath9k_hw_ar9300_set_txpower repeated the output 4 times per line, change it to print the targetPowerValT2 value one per line.

2010-12-08ath: Add and use ath_printk and ath_<level>Joe Perches4-91/+124
Add ath_printk and ath_<level> similar to dev_printk and dev_<level> from device.h This allows a more gradual rename of ath_print to to ath_dbg or perhaps ath_debug. This basically removes debug.h leaving only an #define ath_printk ath_dbg there and moving all the ATH_DBG_<foo> enums to ath.h I do not think there's much purpose for struct ath_common * being passed to the ath_printk functions, but perhaps there might be.

2010-12-07ath9k: fix beacon resource related race conditionRajkumar Manoharan1-14/+7
The beacon tasklet is accesssing the bslot info for beacon generation. Meanwhile the same slot can be freed on interface deletion. Current the remove_interface disables the beacon alert after freeing the slot. This may leads to null pointer access. This patch disables SWBA and kills the beacon tasklet to prevent access to the slot to be freed. After releasing the slot, swba will be enabled again upon the availablity of beaconing interfaces.

2010-12-07ath9k: Fix STA disconnect issue due to received MIC failed bcast framesSenthil Balasubramanian2-3/+9
AR_RxKeyIdxValid will not be set for bcast/mcast frames and so relying this status for MIC failed frames is buggy. Due to this, MIC failure events for broadcast frames are not sent to supplicant resulted in AP disconnecting the STA. Able to pass Wifi Test case 5.2.18 with this fix.

2010-12-07ath9k: fix a DMA related race condition on resetFelix Fietkau3-19/+10
When ath_drain_all_txq fails to stop DMA, it issues a hw reset. This reset happens at a very problematic point in time, when the hardware rx path has not been stopped yet. This could lead to memory corruption, hardware hangs or other issues. To fix these issues, simply remove the reset entirely and check the tx DMA stop status to prevent problems with fast channel changes.

2010-12-07ath9k: fix bug in tx powerMatteo Croce1-4/+8
The ath9k driver subtracts 3 dBm to the txpower as with two radios the signal power is doubled. The resulting value is assigned in an u16 which overflows and makes the card work at full power.

2010-12-07ath5k: Always free tx buffers before resetNick Kossifidis1-2/+4
* Always free tx buffers before reset, since we also empty hw queues. If we don't and a queue gets stuck, we'll never decrease txq_len and sw will keep thinking the queue is still stuck even after reset.

2010-12-02ath9k_hw: fix endian issues with CTLs on AR9003Felix Fietkau4-54/+47
Parsing data using bitfields is messy, because it makes endian handling much harder. AR9002 and earlier got it right, AR9003 got it wrong. This might lead to either using too high or too low tx power values, depending on frequency and eeprom settings. Fix it by getting rid of the CTL related bitfields entirely and use masks instead.

2010-11-30ath5k: Set turbo bit on rf bank 2Nick Kossifidis2-3/+29
* A diff between rfbuffer settings of turbo and non-turbo modes indicates there is a bit on bank 2 related to turbo operation (it's set on turbo modes). This bit is present on all radios except RF5413 that seems to have a completely different bank 2. Also since 2317 has the same rf-registers locations with 2425 and since the bit exists on 2317 I assume it also exists on 2425/2417). So in case we use turbo mode (40MHz) enable it on bank modification. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-11-30ath5k: Clean up turbo mode initvals/rfregsNick Kossifidis5-976/+577

2010-11-30ath5k: No need to save/restore staid flags on resetNick Kossifidis1-21/+1
* Since we set antenna flags on phy init and ack bitrate mode on pcu init, there is no need to save/restore sta_id flags on ath5k_hw_reset.

2010-11-30ath5k: Support synth-only channel change for AR2413/AR5413Nick Kossifidis4-134/+218
* Add synth-only channel change for AR2413/5413. When we call ath5k_reset with a channel ath5k_hw_reset will first try to set channel on PHY while PHY is running instead of doing a normal full reset. To do this phy_init has to change to implement this functionality. * Clean up change_channel flag, what it really did was skip PCU registers when setting initvals. This is done because on reset PCU registers are not affected (except the registers we set in pcu init and -due to hw problems- TSF). Use a new skip_pcu flag that's not misleading instead. In the future we might use that to also skip PCU reset and save us the TSF etc problems (needs testing because standard practice is to reset everything). * Use fast channel change only when setting channel, and set skip_pcu to false only on init. When we reset the card due to DMA or PHY problems skip pcu but never do a fast channel change. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.
