* | ath9k: Add new chanctx eventsSujith Manoharan2014-08-28
| | | | | | | | | | | | | | | | This will be useful in handling addition/change of new channel contexts. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | ath9k: Remove redundant ifdefSujith Manoharan2014-08-28
| | | | | | | | | | | | | | | | | | This was introduced in an earlier patch to handle a compilation warning, but since the channel context code has been mostly isolated, this is not required now.

* | ath9k: Fix channel context variables in ath_softcSujith Manoharan2014-08-28

* | ath9k: Fix 'offchannel' in ath_softcSujith Manoharan2014-08-28
| | | | | | | | | | | | | | | | | | | | | | Finally move the 'offchannel' instance in ath_softc inside a CONFIG_ATH9K_CHANNEL_CONTEXT cage. The offchannel usage in ath9k_calculate_iter_data() is closed off with an ifdef for now, since the state/opmode calculation is common for both the channel context mode and the normal mode.

| | | | | | | | | | | | | | | | | | | | ath9k_vif_iter() was earlier used as an iterator routine when calling a mac80211 utility. This is no longer the case and hence we can mention the argument type explicitly. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | ath9k_htc: advertise support for TDLSCsaba Kiraly2014-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on a quick test with AR9271, TDLS seems to be working fine. Tests were done with 2 Atheros AR9271 based devices with firmware 1.3 (sha1 8d49f928aa40ac53c729189bff1333cd373a7fb5), associated with a WAP54G access point. TDLS worked fine both in WPA2 mode and without encryption. Stations maintained ping flood traffic between each other and towards the AP without significant losses. Not tested with AR7010. TDLS was enabled in earlier patches the same way for other Atheros drivers: ath9k (fd6562344dea2b8b2a5d644cf971f4e56004500a), and carl9170 (d1f3de71a584a82ee4e84505fce9acccf40215ff).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Packets originally buffered for the regular hardware tx queues can end up being transmitted through the U-APSD queue (via PS-Poll or U-APSD). When packets are dropped due to retransmit failures, the pending frames counter is not always updated properly. Fix this by keeping track of the queue that a frame was accounted for in the ath_frame_info struct, and using that on completion to decide whether the counter should be updated. This fixes some spurious transmit queue hangs. Cc: stable@vger.kernel.org Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
