* r8169: revert "Handle rxfifo errors on 8168 chips"françois romieu2010-11-091-2/+3
| | | | | | | | | | | | | | | | | The original patch helps under obscure conditions (no pun) but some 8168 do not like it. The change needs to be tightened with a specific 8168 version. This reverts commit 801e147cde02f04b5c2f42764cd43a89fc7400a2 ("r8169: Handle rxfifo errors on 8168 chips").

* qeth: remove dev_queue_xmit invocationUrsula Braun2010-11-082-54/+8
| | | | | | | | | | | | | For a certain Hipersockets specific error code in the xmit path, the qeth driver tries to invoke dev_queue_xmit again. Commit 79640a4ca6955e3ebdb7038508fa7a0cd7fa5527 introduces a busylock causing locking problems in case of re-invoked dev_queue_xmit by qeth. This patch removes the attempts to retry packet sending with dev_queue_xmit from the qeth driver.

| | | | | | | | | | | | | | | | | | | | If ath5k_hw_attach fails it will free sc->ah (local variable ah) before returning. However, when it reports failure the caller (ath5k_pci_probe) will also free sc->ah. Let the caller handle the deallocation, it does so on further errors as well.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

| * ath9k: add locking for starting the PCU on RXLuis R. Rodriguez2010-10-271-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * ath9k: add locking for stopping RXLuis R. Rodriguez2010-10-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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.
