2011-06-03lib: cordic: add library module providing cordic angle calculationArend van Spriel4-0/+158
The brcm80211 driver in the staging tree has a cordic function to determine cosine and sine for a given angle. Feedback received from John Linville suggested that these kind of functions should be made available to others as a library function in the kernel tree. The b43 driver also has a cordic angle calculation implemented. Cc: linux-kernel@vger.kernel.org Cc: linux-wireless@vger.kernel.org Cc: "John W.

2011-06-03lib: crc8: add new library module providing crc8 algorithmArend van Spriel4-0/+195
The brcm80211 driver in staging tree uses a crc8 function. Based on feedback from John Linville to move this to lib directory, the linux source has been searched. Although there is currently only one other kernel driver using this algorithm (ie. drivers/ssb) we are providing this as a library function for others to use.

The PAN context has three states: disabled, disassociated and associated. It seems that wasn't quite as much of an issue in previous versions of the microcode, but now we really have to use all the three states properly. So add code to switch accordingly.

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.
