Properly mask the value to be written to the register (according to the register size) during the self-test. Otherwise immediate parity error would be generated.

2010-04-20bnx2x: Parity errors handling for 57710 and 57711Vladislav Zolotarov3-56/+1039
This patch introduces the parity errors handling code for 57710 and 57711 chips. HW is configured to stop all DMA transactions to the host and sending packets to the network once parity error is detected, which is meant to prevent silent data corruption. At the same time HW generates the attention interrupt to every function of the device where parity has been detected so that driver can start the recovery flow. The recovery is actually resetting the chip and restarting the driver on all active functions of the chip where the parity error has been reported.

2010-04-15ixgbe: fix bug with vlan strip in promsic modeJesse Brandeburg1-43/+72
The ixgbe driver was setting up 82598 hardware correctly, so that when promiscuous mode was enabled hardware stripping was turned off. But on 82599 the logic to disable/enable hardware stripping is different, and the code was not updated correctly when the hardware vlan stripping was enabled as default. This change comprises the creation of two new helper functions and calling them from the right locations to disable and enable hardware stripping of vlan tags at appropriate times.

2010-04-14ath9k-htc: fix lockdep warning and kernel warning after unplugging ar9271 ↵Ming Lei1-2/+9
usb device This patch fixes two warnings below after unplugging ar9271 usb device: -one is a kernel warning[1] -another is a lockdep warning[2] The root reason is that __skb_queue_purge can't be executed in hardirq context, so the patch forks ath9k_skb_queue_purge(ath9k version of _skb_queue_purge), which frees skb with dev_kfree_skb_any which can be run in hardirq context safely, then prevent the lockdep warning and kernel warning after unplugging ar9271 usb device.

In ath9k-htc register out path, ath9k-htc will pass skb->data into usb hcd and usb hcd will do dma mapping and unmapping to the buffer pointed by skb->data, so we should pass a cache-line aligned address. This patch replace __dev_alloc_skb with alloc_skb to make skb->data pointed to a cacheline aligned address simply since ath9k-htc does not skb_push on the skb and pass it to mac80211, also use kfree_skb to free the skb allocated by alloc_skb(we can use kfree_skb safely in hardirq context since skb->destructor is NULL always in the path).

2010-04-14ath9k-htc:respect usb buffer cacheline alignment in reg in pathMing Lei3-9/+12
In ath9k-htc register in path, ath9k-htc will pass skb->data into usb hcd and usb hcd will do dma mapping and unmapping to the buffer pointed by skb->data, so we should pass a cache-line aligned address. This patch replace __dev_alloc_skb with alloc_skb to make skb->data pointed to a cacheline aligned address simply since ath9k-htc does not skb_push on the skb and pass it to mac80211, also use kfree_skb to free the skb allocated by alloc_skb(we can use kfree_skb safely in hardirq context since skb->destructor is NULL always in the path).

2010-04-14ath5k: treat RXORN as non-fatalBruno Randolf2-1/+15
We get RXORN interrupts when all receive buffers are full. This is not necessarily a fatal situation. It can also happen when the bus is busy or the CPU is not fast enough to process all frames. Older chipsets apparently need a reset to come out of this situration, but on newer chips we can treat RXORN like RX, as going thru a full reset does more harm than good, there. The exact chip revisions which need a reset are unknown - this guess AR5K_SREV_AR5212 ("venice") is copied from the HAL. Inspired by openwrt 413-rxorn.patch: "treat rxorn like rx, reset after rxorn seems to do more harm than good" Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W.

2010-04-14ath5k: Use high bitrates for ACK/CTSBruno Randolf3-6/+5
There was a confusion in the usage of the bits AR5K_STA_ID1_ACKCTS_6MB and AR5K_STA_ID1_BASE_RATE_11B. If they are set (1), we will get lower bitrates for ACK and CTS. Therefore ath5k_hw_set_ack_bitrate_high(ah, false) actually resulted in high bitrates, which i think is what we want anyways. Cleared the confusion and added some documentation.

2010-04-14tun: orphan an skb on txMichael S. Tsirkin1-0/+4
The following situation was observed in the field: tap1 sends packets, tap2 does not consume them, as a result tap1 can not be closed. This happens because tun/tap devices can hang on to skbs undefinitely. As noted by Herbert, possible solutions include a timeout followed by a copy/change of ownership of the skb, or always copying/changing ownership if we're going into a hostile device. This patch implements the second approach. Note: one issue still remaining is that since skbs keep reference to tun socket and tun socket has a reference to tun device, we won't flush backlog, instead simply waiting for all skbs to get transmitted. At least this is not user-triggerable, and this was not reported in practice, my assumption is other devices besides tap complete an skb within finite time after it has been queued. A possible solution for the second issue would not to have socket reference the device, instead, implement dev->destructor for tun, and wait for all skbs to complete there, but this needs some thought, probably too risky for 2.6.34.

2010-04-13bcm63xx_enet: do not overwrite ENET_CTL_REG valueFlorian Fainelli1-1/+3
bcm_enet_hw_preinit will correctly set values in ENET_CTL_REG for internal or external MII operations, however, bcm_enet_open will blindly overwrite the ENET_CTL_REG register value and thus we will loose any changes to it that were made in bcm_enet_hw_preinit, rendering external MII operations non-working. This would lead to the driver not being able to check for link availability on external PHY setups, and thus we would never get to sending packets because link was down from the driver side. This was completely un-noticed because all boards out there but BCM6338-based ones use internal phy on their enet0 interface.
