2011-06-01ath9k: unify edma and non-edma tx code, improve tx fifo handlingFelix Fietkau4-206/+138
EDMA based chips (AR9380+) have 8 Tx FIFO slots, which are used to fix the tx queue start/stop race conditions which have to be worked around for earlier chips by keeping the last descriptor in the queue. The current code stores all frames that do not fit onto the 8 FIFO slots in a separate list. Whenever a FIFO slot is freed up, the next frame (or A-MPDU) from the pending queue gets moved to that slot. This process is not only inefficient, but also unnecessary. The code can be improved visibly by keeping the pending queue fully linked, and moving the contents of the entire queue to a FIFO slot as it becomes available. This patch makes the necessary changes for that and also merges some code that was duplicated for EDMA vs non-EDMA. It changes txq->axq_link to point to the last descriptor instead of the link pointer, so that ath9k_hw_set_desc_link can be used, which works on all chips. With this patch, a small performance increase for non-aggregated traffic was observed on AR9380 based embedded hardware. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2011-05-27wireless: Default to 'n' for 2 new added devices in Kconfig.Tao Ma1-1/+0
We make oldconfig every time when a new kernel arrives, but if we don't have such a device(I guess this is the most common case for a new device), the default value should be 'n' so that the kernel size we build doesn't grow up too much quickly.

2011-05-26ath9k: set 40 Mhz rate only if hw is configured in ht40Rajkumar Manoharan1-1/+2
Whenever there is a channel width change from 40 Mhz to 20 Mhz, the hardware is reconfigured to ht20. Meantime before doing the rate control updation, the packets are being transmitted are selected rate with IEEE80211_TX_RC_40_MHZ_WIDTH. While transmitting ht40 rate packets in ht20 mode is causing baseband panic with AR9003 based chips. ==== BB update: BB status=0x02001109 ==== ath: ** BB state: wd=1 det=1 rdar=0 rOFDM=1 rCCK=1 tOFDM=0 tCCK=0 agc=2 src=0 ** ath: ** BB WD cntl: cntl1=0xffff0085 cntl2=0x00000004 ** ath: ** BB mode: BB_gen_controls=0x000033c0 ** ath: ** BB busy times: rx_clear=99%, rx_frame=0%, tx_frame=0% ** ath: ==== BB update: done ==== Cc: stable@kernel.org Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.

2011-05-19ath9k: fix ad-hoc mode beacon selectionFelix Fietkau1-12/+20
In ad-hoc mode, beacon timers are configured differently compared to AP mode, and (depending on the scenario) can vary enough to make the beacon tasklet not detect slot 0 based on the TSF. Since staggered beacons are not (and cannot be) used in ad-hoc mode, it makes more sense to just hardcode slot 0 here, avoiding unnecessary TSF reads and calculations.
