2015-03-16ath9k: fix tracking of enabled AP beaconsFelix Fietkau1-1/+1
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.

RSSI is being stored internally as s8 in several places. The indication of an unset RSSI value, ATH_RSSI_DUMMY_MARKER, was supposed to have been set to 127, but ended up being set to 0x127 because of a code cleanup mistake.

2010-11-15ath9k: rework tx queue selection and fix queue stopping/wakingFelix Fietkau1-4/+5
The current ath9k tx queue handling code showed a few issues that could lead to locking issues, tx stalls due to stopped queues, and maybe even DMA issues. The main source of these issues is that in some places the queue is selected via skb queue mapping in places where this mapping may no longer be valid. One such place is when data frames are transmitted via the CAB queue (for powersave buffered frames). This is made even worse by a lookup WMM AC values from the assigned tx queue (which is undefined for the CAB queue). This messed up the pending frame counting, which in turn caused issues with queues getting stopped, but not woken again. To fix these issues, this patch removes an unnecessary abstraction separating a driver internal queue number from the skb queue number (not to be confused with the hardware queue number). It seems that this abstraction may have been necessary because of tx queue preinitialization from the initvals. This patch avoids breakage here by pushing the software <-> hardware queue mapping to the function that assigns the tx queues and redefining the WMM AC definitions to match the numbers used by mac80211 (also affects ath9k_htc). To ensure consistency wrt. pending frame count tracking, these counters are moved to the ath_txq struct, updated with the txq lock held, but only where the tx queue selected by the skb queue map actually matches the tx queue used by the driver for the frame.

ath9k supports the AR5008, AR9001 and AR9002 family of Atheros chipsets, all 802.11n. The new breed of 802.11n chips, the AR9003 family will be supported as well soon.

Software padding is done on the TX path and software unpadding is done on the RX path. This patch corrects the position where the padding occurs. A specific function computes the pad position and this function is used in the TX and RX path.

2009-11-28ath9k: fix processing of TX PS null data framesLuis R. Rodriguez1-0/+1
When mac80211 was telling us to go into Powersave we listened and immediately turned RX off. This meant hardware would not see the ACKs from the AP we're associated with and hardware we'd end up retransmiting the null data frame in a loop helplessly. Fix this by keeping track of the transmitted nullfunc frames and only when we are sure the AP has sent back an ACK do we go ahead and shut RX off.

2009-11-11ath9k_common: add new module to share 802.11n driver helpersLuis R. Rodriguez1-0/+123
ath9k and ath9k_htc share a lot of common hardware characteristics. They only differ in that ath9k_htc works with a target CPU and ath9k works directly with the hardware. ath9k_htc will do *some* things in the firmware, but a lot of others on the host. The common 802.11n hardware code is already shared through the ath9k_hw module. Common helpers amongst all Atheros drivers can use the ath module, this includes ath5k and ar9170 as users. But there is some common driver specific helpers which are not exactly hardware code which ath9k and ath9k_htc can share. We'll be using ath9k_common for this to avoid bloating the ath module and the common 802.11n hardware module ath9k_hw. We start by sharing skb pre and post processing in preparation for a hand off to mac80211. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.
