2013-01-22drivers/net: delete Racal Interlan ISA ni52 (i825xx) driverPaul Gortmaker5-1672/+0
Like the other drivers that were in the ISA i825xx family, the ni52 was rather rare, not widely used, and hence perhaps not as reliable as the more mainstream ISA drivers that were heavily used. Given that, it is chosen for retirement at this time as well. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2013-01-22drivers/net: delete intel i825xx based znet notebook driverPaul Gortmaker3-939/+0
This driver supported early to mid 1990's Zenith laptops, of the 2" thick variety. The driver was already dead 10+ years ago, but we see this in the source: ---------------- /* 10/2002 [...] Tested on a vintage Zenith Z-Note 433Lnp+. Probably broken on anything else. Testers (and detailed bug reports) are welcome :-). ---------------- To clarify, a 433 translates into a 486 at 33MHz, and a system with a default of 4MB RAM. I can't fault the noble effort to keep things working a decade ago, but at this point in time, there is no valid justification to continue carrying this driver along. Note that there is no associated Space.c cleanup here since this driver was using module_init to hook itself in. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2013-01-22drivers/net: delete ISA intel eexpress and eepro i825xx driversPaul Gortmaker6-3699/+0
These old drivers should not be confused with the very common PCI cards that are supported by e100.c -- these older 10Mbit ISA only drivers were not as commonly used as some of the other ISA drivers, simply due to hardware availability and pricing. Given the rarity of the hardware, and the subsequent less extensive use of the drivers, it makes sense to obsolete them at this point in time, along with other rare/experimental ISA drivers.

2013-01-22drivers/net: delete the 3Com 3c505/3c507 intel i825xx supportPaul Gortmaker6-2936/+0
For those of us who were around in the early to mid 1990's, we will remember that the i825xx ethernet support was not something that was considered sufficiently vetted for 24/7 use. Folks might be inclined to use *functional* ISA hardware on some near expired P3 ISA machines for dedicated workhorse applications, but the odds of using (and relying on) one of these old/experimental drivers is essentially nil. So lets remove them. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2013-01-22drivers/net: delete old parallel port de600/de620 driversPaul Gortmaker7-1846/+2
The parallel port is largely replaced by USB, and even in the day where these drivers were current, the documented speed was less than 100kB/s. Let us not pretend that anyone cares about these drivers anymore, or worse - pretend that anyone is using them on a modern kernel. As a side bonus, this is the end of legacy parallel port ethernet, so we get to drop the whole chunk relating to that in the legacy Space.c file containing the non-PCI unified probe dispatch.

2013-01-22drivers/net: delete old 8bit ISA 3c501 driver.Paul Gortmaker5-1007/+0
It was amusing that linux was able to make use of this 1980's technology on machines long past its intended lifespan, but it probably should go now. To set some context, the 3c501 was designed in the 1980's to be used on 8088 PC-XT 8bit ISA machines. It was built using a large number of discrete TTL components and truly looks like a relic of the ancient past before large scale integration was common. But from a functional point of view, the real issue, as stated in the (also obsolete) Ethernet-HowTo, is that "...the 3c501 can only do one thing at a time -- while you are removing one packet from the single-packet buffer it cannot receive another packet, nor can it receive a packet while loading a transmit packet." You know things are not good when the Kconfig help text suggests you make a cron job doing a ping every minute. Hardware that old and crippled is simply not going to be used by anyone in a time where 10 year old 100Mbit PCI cards (that are still functional) are largely give-away items.

2013-01-22drivers/net: delete intel 486 panther onboard ethernet supportPaul Gortmaker3-1346/+0
This driver was specific to a "professional workstation" line of products from around 1993 that used the i82596 ethernet chip as an on-board ethernet solution. With a 486 processor, and the premium top of the line model maxing out at a clock speed of 50MHz, we can safely retire this support. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2013-01-22drivers/net: delete 486 Apricot supportPaul Gortmaker4-99/+9
The Apricot was a 486 PC with 4MB RAM, and an on-board ethernet via an intel i82596 hard-wired to i/o 0x300. Those who were using linux in the 1990's will recall that the i82596 driver was not one of the more stable or widely used drivers of its day. Combine that with the extremely limited resources of the platform, and it is truly time to expire the support for this thing. There are some old m68k targets who were also using this chip, so rather than poll the m68k user base, we simply cut out the x86/Apricot support here in this commit.

The existing port isolation mode 'forward' will now verify that the adjacent switch port supports the required reflective relay (RR) mode. This patch adds the required error handling for the cases where enabling port isolation mode 'forward' can now fail. Furthermore, once established, we never fall back from one of the port isolation modes to a non-isolated mode without further user-interaction. This includes cases where the isolation mode was enabled successfully, but ceases to work e.g. due to configuration changes at the switch port. Finally, configuring an isolation mode with the device being offline will make onlining the device fail permanently upon errors encountered until either errors are resolved or the isolation mode is changed by the user to a different mode.

2013-01-19ixgbe: Improve performance and reduce size of ixgbe_tx_mapAlexander Duyck1-23/+19
This change is meant to both improve the performance and reduce the size of ixgbe_tx_map. To do this I have expanded the work done in the main loop by pushing first into tx_buffer. This allows us to pull in the dma_mapping_error check, the tx_buffer value assignment, and the initial DMA value assignment to the Tx descriptor. The net result is that the function reduces in size by a little over a 100 bytes and is about 1% or 2% faster.

2013-01-19ixgbe: Update ixgbe Tx flags to improve code efficiencyAlexander Duyck3-53/+57
This change is meant to improve the efficiency of the Tx flags in ixgbe by aligning them with the values that will later be written into either the cmd_type or olinfo. By doing this we are able to reduce most of these functions to either just a simple shift followed by an or in the case of cmd_type, or an and followed by an or in the case of olinfo. To do this I also needed to change the logic and/or drop some flags. I dropped the IXGBE_TX_FLAGS_FSO and it was replaced by IXGBE_TX_FLAGS_TSO since the only place it was ever checked was in conjunction with IXGBE_TX_FLAGS_TSO. I replaced IXGBE_TX_FLAGS_TXSW with IXGBE_TX_FLAGS_CC, this way we have a clear point for what the flag is meant to do. Finally the IXGBE_TX_FLAGS_NO_IFCS was dropped since were are already carrying the data for that flag in the skb. Instead we can just check the bitflag in the skb. In order to avoid type conversion errors I also adjusted the locations where we were switching between CPU and little endian.

2013-01-18net: ethernet: davinci_cpdma: Add boundary for rx and tx descriptorsMugunthan V N4-13/+57
When there is heavy transmission traffic in the CPDMA, then Rx descriptors memory is also utilized as tx desc memory looses all rx descriptors and the driver stops working then. This patch adds boundary for tx and rx descriptors in bd ram dividing the descriptor memory to ensure that during heavy transmission tx doesn't use rx descriptors. This patch is already applied to davinci_emac driver, since CPSW and davici_dmac shares the same CPDMA, moving the boundry seperation from Davinci EMAC driver to CPDMA driver which was done in the following commit commit 86d8c07ff2448eb4e860e50f34ef6ee78e45c40c Author: Sascha Hauer <s.hauer@pengutronix.de> Date: Tue Jan 3 05:27:47 2012 +0000 net/davinci: do not use all descriptors for tx packets The driver uses a shared pool for both rx and tx descriptors. During open it queues fixed number of 128 descriptors for receive packets. For each received packet it tries to queue another descriptor. If this fails the descriptor is lost for rx. The driver has no limitation on tx descriptors to use, so it can happen during a nmap / ping -f attack that the driver allocates all descriptors for tx and looses all rx descriptors. The driver stops working then. To fix this limit the number of tx descriptors used to half of the descriptors available, the rx path uses the other half.

2013-01-18igb: Use in-kernel PTP_EV_PORT #defineMatthew Vick1-3/+3
Rather than use an extra #define for something that already exists, use the kernel #define for the PTP port.

2013-01-18igb: Free any held skb that should have been timestamped on removeMatthew Vick1-0/+4
To prevent a race condition where an skb has been saved to return the Tx timestamp later and the driver is removed, add a check to determine if we have an skb stored and, if so, free it.

2013-01-18igb: Add mechanism for detecting latched hardware Rx timestampMatthew Vick4-0/+51
Add a check against possible Rx timestamp freezing in the hardware via watchdog mechanism. This situation can occur when an Rx timestamp has been latched, but the packet has been dropped because the Rx ring is full. Whenever a packet comes in that should be timestamped, the Rx timestamp gets latched into the hardware registers and we will store the jiffy value in the rx_ring. The watchdog will keep track of his own jiffy timer whenever there is no valid timestamp in the registers. If the watchdog detects a valid timestamp in the registers, meaning that no Rx packet has consumed it yet, it will check which time is most recent: the last time in the watchdog or any time in the rx_rings. If the most recent "event" was more than 5 seconds ago, it will flush the Rx timestamp and print a warning message to the syslog.

2013-01-18igb: Add timeout for PTP Tx work itemMatthew Vick4-0/+14
When transmitting a packet that must return a Tx timestamp, a work item gets scheduled to poll for the Tx timestamp being completed in hardware. Add a timeout on this work item of 15 seconds from when the driver gets the skb, after which it will stop polling. Report via stats and system log if this occurs.
