2013-09-26ath9k: Fix issue with parsing malformed CFP IESujith Manoharan2-2/+6
All QCA chips have the ability to parse the CF Parameter Set IE in beacons. If the IE is malformed in the beacons from some APs [1], the HW locks up. In AP mode, a beacon stuck would happen and in client mode, a disconnection usually is the result. To fix this issue, set the AR_PCU_MISC_MODE2_CFP_IGNORE to ignore the CFP IE in beacons - this is applicable for all chips. For AP mode, if this issue happens, the NAV is also corrupted and has to be reset - this will be done in a subsequent patch.

2013-09-26ath9k: Fix calibration for AR9462Sujith Manoharan1-0/+15
TX IQ calibration is disabled by default for AR9462, this is done using the initvals (reg 0xa644). But, to compensate for this, the AR_PHY_RX_DELAY register should be set to the max allowed value when performing calibration.

2013-09-26ath10k: align RX frames properlyMichal Kazior1-1/+5
Ethernet-like decapping mode leaves IP protocol frame not aligned to 4-byte boundaries. This leads to re-aligning in mac80211 which in turn leads to poor CPU cache behaviour on some machines. Since HW doesn't allow to change payload offset properly the solution is to force HW to decap in Native Wifi mode which always has 24-bytes long 802.11 header (even for QoS frames). This means IP frame is properly aligned in this decap mode. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2013-09-26ath10k: fix Native Wifi decap mode RXMichal Kazior1-3/+29

2013-09-26ath10k: report A-MSDU subframes individuallyMichal Kazior2-123/+85
HW reports each A-MSDU subframe as a separate sk_buff. It is impossible to configure it to behave differently. Until now ath10k was reconstructing A-MSDUs from subframes which involved a lot of memory operations. This proved to be a significant contributor to degraded RX performance.

2013-09-25ath: Remove extern from function prototypesJoe Perches4-12/+10
There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

2013-09-20ath10k: use msdu headroom to store txfragMichal Kazior4-53/+53
Instead of allocating sk_buff for a mere 16-byte tx fragment list buffer use headroom of the original msdu sk_buff. This decreases CPU cache pressure and improves performance.

Until now the all MSDU transfer related structures were freed when all resources were unreferenced. Now HTC transfer is freed independently and HTT transfer is so too.

Commit e9bb0aa39 ("ath10k: delete struct ce_sendlist") broke num_sends_allowed incrementing. num_sends_allowed exceeded initial values and could overflow.

2013-09-16ath10k: simplify HTC command submittingMichal Kazior3-140/+43
The patch removes HTC endpoint tx workers in favour of direct command submission. This makes a lot more sense for data path. mac80211 queues are effectively stopped/woken up in a more timely fashion preventing build up of frames. It's possible to push more traffic than the device/system is able to handle and have no hiccups or performance degradation with UDP traffic. WMI commands will now report errors properly and possibly block as they actively can wait for tx credits to become available.
