"vif" is assigned twice. We can remove the first one. This silences a Smatch warning that "ctx" could be one step past the end of the priv->contexts[] array. Signed-off-by:

The calls to kzalloc() weren't checked here and it upsets the static checkers. Obviously they're not super likely to fail, but we might as well add some error handling. Signed-off-by:

When this flag is set, Tx A-MPDU sessions will not be started by mac80211. This flag is required for devices that support Tx A-MPDU setup in hardware. Signed-off-by:

Removing unnecessary messages saves code and text. Site specific OOM messages are duplications of a generic MM out of memory message and aren't really useful, so just delete them. Signed-off-by:

When an interface is removed, the mesh paths associated with it should also be removed. This fixes a bug we observed when reloading a device driver module without reloading mac80211s. Signed-off-by:

The commit "ath9k_hw: Fix exceed transmission burst-time of 5GHz" added a padding of 60 delimiters on the first subframe to work around an issue on AR9380, but it lacked the checks to prevent it from being applied to pre-AR9380, enterprise AR9380 or AR9580+ Signed-off-by:

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:
