This will avoid mac80211 to trigger PS mode for connected station based on the PM bit of incoming frames. AP firmware is capable of handling such frames and buffering TX frames destined to the stations that are in PS mode. Signed-off-by:

When the rssi of the current AP drops, both wpa_supplicant and the firmware may do a background scan to find a better AP and try to associate. Since firmware based roaming is faster, inform wpa_supplicant to avoid roaming and let the firmware decide to roam if necessary. For fullmac drivers like ath6kl, it is just enough to provide the ESSID and the firmware will decide on the BSSID. Since it is not possible to do pre-auth during roaming for fullmac drivers, the wpa_supplicant needs to completely disconnect with the old AP and reconnect with the new AP. This consumes lot of time and it is better to leave the roaming decision to the firmware. Signed-off-by:

Unfortunately failed BAR tx attempts happen more frequently than I expected, and the resulting aggregation teardowns cause performance issues, as the aggregation session does not always get re-established properly. Instead of tearing down the entire aggr session, we can simply store the SSN of the last failed BAR tx attempt, wait for the first successful tx status event, and then send another BAR with the same SSN.

It is only used to workaround interoperability issues related to longer delays in receiving the block ack, so it is not necessary to apply it to the CTS exchange. Should improve throughput slightly, especially when there are lots of retransmissions. Signed-off-by:

Under failure conditions, the mesh stack sends PERR messages to the previous sender of the failed frame. This happens in the tx feedback path, in which the transmission queue lock may be taken. Avoid a deadlock by sending the path error via the pending queue. Signed-off-by:

With sequence number and buffer allocation deferred to when they're needed for the first time, it becomes much easier to start dropping packets from the tid queue if necessary, e.g. when latency suddenly increases. This can lead to some future improvements in buffer management for better latency. Signed-off-by:

The recent commit "ath9k: Send legacy rated frames as unaggregated" introduced a check to ensure that packets with non-MCS rates set in the rate series will not be aggregated. However, it failed to check if the rate series is valid before testing the flags, thus breaking aggregation for normal MCS-only packets if the last series is unset. Signed-off-by:

For AR9287 v1.3+ chips, MAC runs at 117MHz. But the initvals IFS parameters are loaded based on 44/88MHz clockrate. So eifs/usec from ini should not be used for AR9287 v1.3+. The mentioned values are tested on 2 chain HT40 mode. Signed-off-by:

When 64-bit DMA was first used, there were problems with the BCM4311 (14e4:4311). The problem was "fixed" by using the GFP_DMA flag in the allocation of coherent ring descriptor memory. The original problem is now believed to have been due to bugs in the 64-bit DMA implementation in the rest of the kernel, and that those bugs have been fixed. Accordingly, the requirement for the descriptors to be in the DMA zone is relaxed. Bounce buffers are left in the DMA zone. Signed-off-by:

In order to implement support for GO powersave on the P2P client side, the ucode needs to know what GO we're trying to authenticate/associate with, it needs to have a station entry and the BSSID in the RXON set. Implement the new mac80211 callbacks to give this data to the device. Since this is also useful for the device when a normal connection is established, also program it with the information in that case. Signed-off-by:

This logic is responsible to tell mac80211 when the HW queues are empty and the BA session can be started / torn down. Fix a bug on the way: When the the Tx BA session is stopped and the HW queues aren't empty, we stop the SW queue to drain the HW queue and then switch to the legacy HW queue. This is the IWL_EMPTYING_HW_QUEUE_DELBA state. While in this state, we never wake the SW queue, even when the HW queue is almost empty, since we need to drain it completely. Look at iwl_trans_pcie_reclaim regarding this. Once the HW queue is really empty, we must wake the SW queue in order to get traffic to the legacy queue. This step was missing leading to an odd situation were the traffic would just stall after we tore down a Tx BA session while the HW queue was not empty. Signed-off-by:
