2015-05-03ath9k: fix per-packet tx power configurationLorenzo Bianconi1-27/+25
Do not use ieee80211_vif pointer in ath_get_rate_txpower() since it has been overwritten by setup_frame_info() and it will result in a corrupted tx power configuration. Set per-packet tx power in setup_frame_info() according to current vif tx power. Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi83@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-04-24mac80211: remove support for IFF_PROMISCJohannes Berg4-17/+3
This support is essentially useless as typically networks are encrypted, frames will be filtered by hardware, and rate scaling will be done with the intended recipient in mind. For real monitoring of the network, the monitor mode support should be used instead. Removing it removes a lot of corner cases. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-04-07ath9k: add extra GPIO led supportMiaoqing Pan4-3/+27
ar9550 or later chips, the AR_GPIO_IN_OUT register only can control GPIO[0:3]. For the extra GPIO, use standard GPIO calls instead of WMAC internal registers. Signed-off-by: Miaoqing Pan <miaoqing@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-04-07ath9k_htc: check seq number instead of cmd id for timeoutFred Chou2-7/+7
As the driver may send multiple wmi commands with identical cmd id, it is more robust to check seq number for timeout instead. Signed-off-by: Fred Chou <fred.chou.nd@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

In 'net' we added a READ_ONCE() to the socket cached RX route read, whilst in 'net-next' Eric Dumazet touched the surrounding code dealing with how mini sockets are handled. With USB, it's a case of the same bug fix first going into net-next and then I cherry picked it back into net. Signed-off-by: David S. Miller <davem@davemloft.net>

2015-03-16ath9k: disable TPC support again (for now)Felix Fietkau1-1/+1

2015-03-16ath9k: fix tracking of enabled AP beaconsFelix Fietkau2-9/+13
sc->nbcnvifs tracks assigned beacon slots, not enabled beacons. Therefore, it cannot be used to decide if cur_conf->enable_beacon (bool) should be updated, or if beacons have been enabled already. With the current code (depending on the order of calls), beacons often do not get enabled in an AP+STA setup. To fix tracking of enabled beacons, convert cur_conf->enable_beacon to a bitmask of enabled beacon slots.
