| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the driver increments the tx_timeout counter (an error counter) when simply resetting the part with outstanding transmit work pending. This is an unnecessary count of an error, when all we should be doing is just resetting the part and discarding the transmits. With this change the only increment of tx_timeout is when the stack calls the watchdog reset function due to a true Tx timeout.

| * | r8169: RxFIFO overflow oddities with 8168 chipsets.Francois Romieu2011-02-041-9/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some experiment-based action to prevent my 8168 chipsets locking-up hard in the irq handler under load (pktgen ~1Mpps). Apparently a reset is not always mandatory (is it at all ?). - RTL_GIGA_MAC_VER_12 - RTL_GIGA_MAC_VER_25 Missed ~55% packets. Note: - this is an old SiS 965L motherboard - the 8168 chipset emits (lots of) control frames towards the sender - RTL_GIGA_MAC_VER_26 The chipset does not go into a frenzy of mac control pause when it crashes yet but it can still be crashed. It needs more work. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> Cc: Ivan Vecera <ivecera@redhat.com> Cc: Hayes <hayeswang@realtek.com>
| * | r8169: use RxFIFO overflow workaround for 8168c chipset.Ivan Vecera2011-02-041-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I found that one of the 8168c chipsets (concretely XID 1c4000c0) starts generating RxFIFO overflow errors. The result is an infinite loop in interrupt handler as the RxFIFOOver is handled only for ...MAC_VER_11. With the workaround everything goes fine.

| * | niu: Fix races between up/down and get_stats.David S. Miller2011-02-031-16/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Flavio Leitner, there is no synchronization to protect NIU's get_stats method from seeing a NULL pointer in either np->rx_rings or np->tx_rings. In fact, as far as ->ndo_get_stats is concerned, these values are set completely asynchronously. Flavio attempted to fix this using a RW semaphore, which in fact works most of the time. However, dev_get_stats() can be invoked from non-sleepable contexts in some cases, so this fix doesn't work in all cases. So instead, control the visibility of the np->{rx,tx}_ring pointers when the device is being brough up, and use properties of the device down sequence to our advantage. In niu_get_stats(), return immediately if netif_running() is false. The device shutdown sequence first marks the device as not running (by clearing the __LINK_STATE_START bit), then it performans a synchronize_rcu() (in dev_deactive_many()), and then finally it invokes the driver ->ndo_stop() method. This guarentees that all invocations of niu_get_stats() either see netif_running() as false, or they see the channel pointers before ->ndo_stop() clears them out. If netif_running() is true, protect against startup races by loading the np->{rx,tx}_rings pointer into a local variable, and punting if it is NULL. Use ACCESS_ONCE to prevent the compiler from reloading the pointer on us. Also, during open, control the order in which the pointers and the ring counts become visible globally using SMP write memory barriers. We make sure the np->num_{rx,tx}_rings value is stable and visible before np->{rx,tx}_rings is. Such visibility control is not necessary on the niu_free_channels() side because of the RCU sequencing that happens during device down as described above. We are always guarenteed that all niu_get_stats calls are finished, or will see netif_running() false, by the time ->ndo_stop is invoked.

| | * ath9k: Fix power save usage count imbalance on deinitRajkumar Manoharan2011-01-282-2/+2

But it is failed to restore the ps_usecount after that. The problem is that the chip is forcibly moved to FULL SLEEP by radio_disable when mac80211 is reporting as idle though ps_usecount is not zero. This patch retores ps_usecount properly and ensures that the chip is always moved to full sleep only if ps usage count is zero which also helps in debugging deadbeef on multivif case. And also fixes the following warning. ath: DMA failed to stop in 10 ms AR_CR=0xdeadbeef AR_DIAG_SW=0xdeadbeef ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath9k/recv.c:536 ath_stoprecv+0xf4/0x100 [ath9k]() Cc: stable@kernel.org Cc: Paul Stewart <pstew@google.com> Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.
