9b674a0207 ath9k_htc: Add TSF adjust capability
In multi-interface mode, beacons/probe responses that are

d0805c1c57 mwl8k: use traffic threshold to decide when to start ampdu
Currently, ampdu stream is created on the first qos packet to an
HT sta. The overhead of setting up the BA session may not be
justified if the outgoing packet rate is minimal (e.g., ping). So
we only allow ampdu streams after seeing a critical number of
packets in an arbitrary one-second interval.

8e26a03036 ath9k: introduce ATH9K_{PCI,AHB} config options
Currently ath9k only available in menuconfig if PCI bus
support is enabled. However the driver is required for
the built-in wireless MACs of the Atheros AR9130/AR9132
SoCs. These SoCs have no PCI controller, the wireless
MAC is connected to the AHB bus on them.

Introduce separated config options for the supported
buses, in order to allow building of ath9h without PCI
bus support.

As a bonus, this patch removes the cross-reference of
the ATHEROS_AR71XX option which is not present in the
kernel.

6d7b97b23e ath5k: fix tx status reporting issues
During normal operation, minstrel was showing suspicious EWMA probabilities
exceeding 100%. It looks like the tx status reporting in ath5k was not
properly clearing the rate index for rates which were never attempted.

This is caused by uninitialized stale data in the on-stack tx status
information, which is reused when more frames are received.

To fix this, rely on ts->ts_final_idx to select the last attempted rate,
instead of checking whether ts->ts_rate is set.

Additionally, the conversion from the driver rate index back to the
mac80211 rate index can be dropped, as the mac80211 tx status will still
have the original rate index which was used to set up the descriptor.

Additionally, one more inaccuracy was fixed - the final rate attempt
count only needs to be increased by one if the transmission attempt was
successful.
