2011-10-14iwlagn: fix a race in the unmapping of the TFDsEmmanuel Grumbach
While inspecting the code, I saw that iwl_tx_queue_unmap modifies the read pointer of the Tx queue without taking any locks. This means that it can race with the reclaim flow. This can possibly lead to a DMA warning complaining that we unmap the same buffer twice. This is more a W/A than a fix since it is really weird to take sta_lock inside iwl_tx_queue_unmap, but it can help until we revamp the locking model in the transport layer.

2011-10-14iwlagn: stop interrupts when suspendingJohannes Berg
Occasionally, the device will send interrupts while it is resuming, at a point where we are not set up again to handle them. This causes the core IRQ handling to completely disable the IRQ, and then the driver won't work again until it is reloaded/rebound. To fix this issue disable the IRQ on suspend, this will cause us to only get interrupts again after we've setup everything on resume.

2011-10-14iwlagn: send simple LQ command for WoWLANJohannes Berg

2011-10-14iwlagn: don't assign seqno to QoS Null framesJohannes Berg
802.11 says: "Sequence numbers for QoS (+)Null frames may be set to any value." However, if we use the normal counters then peers will get confused with aggregation since there'll be holes in the sequence number sequence. To avoid that, don't assign sequence numbers to QoS Null frames. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi GUy <wey-yi.w.guy@intel.com> Signed-off-by: John W.

2011-10-14iwlagn: update beacon smarterJohannes Berg
Updating the beacon every time right after one was transmitted is pointless, most of the time we might not even have to update it. We will update it every time it changes, which includes from set_tim(), a callback iwlwifi didn't implement so far. This also reduces latency for clients, previously we would update the beacon right after the previous one was transmitted, and then a TIM change would only take effect after that again -- updating the beacon right after the TIM changes makes the TIM change go out to the air faster.

2011-10-14libata: make ata_sff_data_xfer_noirq() work with 32-bit PIOBartlomiej Zolnierkiewicz
Always use ata_sff_data_xfer32() in ata_sff_data_xfer_noirq() so the latter can be also used for host controllers supporting 32-bit PIO operations. It is a completely safe thing to do because if 32-bit PIO is not supported or enabled ata_sff_data_xfer32() will fallback to a standard method.
