2010-10-30can: pch_can: fix section mismatch warning by using a whitelisted nameMarc Kleine-Budde
This patch fixes the following section mismatch warning: WARNING: drivers/net/can/pch_can.o(.data+0x18): Section mismatch in reference from the variable pch_can_pcidev to the variable .devinit.rodata:pch_pci_tbl The variable pch_can_pcidev references the variable __devinitconst pch_pci_tbl This is actually a false positive which is fixed by giving the offending variable a whitelisted name, it's renamed to "pch_can_pci_driver". This makes sense because the variable is of the type "struct pci_driver".

2010-10-29libertas: Fix sd8686 firmware reloadPaul Fox
For the SD8686, we cannot rely on the scratch register to read the firmware load status, because the same register is used for storing RX packet length. Broaden the check to account for this. The module can now be unloaded/reloaded successfully. Based on the implementation from libertas_tf.

The index variable to access the rate flags should be obtained from the inner loop counter which corresponds to the rate table structure.This fixes the invalid rate selection i.e when the supported basic rate is invalid on a particular band and also the following warning message.

2010-10-28stmmac: enable/disable rx/tx in the core with a single write.avisconti
This patch enables and disables the rx and tx bits in the MAC control reg by using a single write operation. This also solves a possible problem (spotted on SPEAr platforms) at 10Mbps where two consecutive writes to a MAC control register can take more than 4 phy_clk cycles.

2010-10-28ixgbe: DCB, fix TX hang occurring in stress condition with PFCJohn Fastabend
The DCB credits refill quantum _must_ be greater than half the max packet size. This is needed to guarantee that TX DMA operations are not attempted during a pause state. Additionally, the min IFG must be set correctly for DCB mode. If a DMA operation is requested unexpectedly during the pause state the HW data store may be corrupted leading to a DMA hang. The DMA hang requires a reset to correct. This fixes the HW configuration to avoid this condition.

(Applied over Eric's "ehea: fix use after free" patch) Currently ehea stats are broken. The bytes counters are got from the hardware, while the packets counters are got from the device driver. Also, the device driver counters are resetted during the the down process, and the hardware aren't, causing some weird numbers. This patch just consolidates the packets and bytes on the device driver.

2010-10-27ath9k: fix tx aggregation flush on AR9003Felix Fietkau
Completing aggregate frames can lead to new buffers being pushed into the tid queues due to software retransmission. When the tx queues are being drained, all pending aggregates must be completed before the tid queues get drained, otherwise buffers might be leaked.

2010-10-27ath9k: lock reset and PCU start/stoppingLuis R. Rodriguez
Apart from locking the start and stop PCU we need to ensure we also content starting and stopping the PCU between hardware resets.

2010-10-27ath9k: rename rxflushlock to pcu_lockLuis R. Rodriguez
The real way to lock RX is to contend on the PCU and reset, this will be fixed in the next patch but for now just do the renames so that the next patch which changes the locking order is crystal clear.

2010-10-27ath9k: add locking for starting the PCU on RXLuis R. Rodriguez
There was some locking for starting some parts of RX but not for starting the PCU. Include this otherwise we can content against stopping the PCU. This can potentially lead to races against different buffers on the PCU which can lead to to the DMA RX engine writing to buffers which are already freed.

2010-10-27ath9k: add locking for stopping RXLuis R. Rodriguez
ath9k locks for starting RX but not for stopping RX. We could potentially run into a situation where tried to stop RX but immediately started RX. This allows for races on the the RX engine deciding what buffer we last left off on and could potentially cause ath9k to DMA into already free'd memory or in the worst case at a later time to already given memory to other drivers. Fix this by locking stopping RX.

open()/close() When async mcc compls are rcvd on an i/f that is down (and so interrupts are disabled) they just lie unprocessed in the compl queue.The compl queue can eventually get filled up and cause the BE to lock up.The fix is to use be_worker to reap mcc compls when the i/f is down.be_worker is now launched in be_probe() and canceled in be_remove().
