2012-04-17ath9k: Fix TX fragmentationSujith Manoharan1-1/+9
Assigning sequence number for frames without taking care of the fragment field breaks transmission of fragmented frames. Fix this by assigning the fragment number properly. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2012-04-16ath9k: introduce ath9k_hw_get_scaled_power helperGabor Juhos5-75/+44
The computation of the scaled power value in various eeprom files uses identical code. Move that code into a helper function and use that instead of code duplication. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-04-16ath9k: use consistent value for REDUCE_SCALED_POWER_BY_THREE_CHAINGabor Juhos3-4/+4
The REDUCE_SCALED_POWER_BY_THREE_CHAIN symbol is defined in different eeprom files, and the value varies between the different files. In eeprom_def.c and in ar9003_eeprom.c the value of the symbol is 9, however the comments in these files indicates the value should be 10*log10(3)*2 which is 9.54242509439325. Replace the the value to 10 in these files. Also add comments to eeprom_9287.c. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2012-04-16ath9k: fix beacon descriptorRajkumar Manoharan1-1/+1
The tx interrupt for beacon queue is configured only for edma chips. As the edma chip does not support per descriptor interrupt, no need to set INTREQ for every beacon descriptor. And also clear ps filter for beacon frame. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Sync-up ibss beacon timer with the beacon frame's timestamp. When the node acts as joiner, it has to sync with the received beacon timestamp instead of reading tsf from hw. As the hw tsf wont wont be update till bssid is configured. This patch programs hw tsf with the received beacon timestamp if beacon timers are yet to be configured.

Following Felix's recent patchset as an example I have replaced memcmp with compare_ether_addr.

2012-04-16ath6kl: list_first_entry() is never NULLDan Carpenter1-8/+0
We can remove the NULL check here. It triggers a Smatch warning because list_first_entry() never is NULL and people who check for it normally intend to check for list_empty() instead.

2012-04-13ath9k_hw: Remove BTCOEX initvalsSujith Manoharan3-20/+0
The MAX_TXPWR table for BTCOEX is not needed for AR9462. Programming these values to the HW results in undesirable behavior - for example, large number of delimiter/data underruns are seen in AES-CCMP mode. Also, registers like AR_PCU_MISC_MODE2 return 0xdeadbeef after the BTCOEX_MAX power table is programmed to the HW, and frames being transmitted end up being looped back to the RX engine, an example being beacon frames in IBSS mode. Remove this table for now - this fixes CCMP performance and general IBSS usage. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

This adds a DFS pattern detector to ath9k. It is fed with pulse events by the radar pulse detector and reports in place whether a pattern was detected. On detection, the result is reported as radar event to the DFS management component in the upper layer. Currently the ETSI DFS domain is supported with detector lines for the patterns defined by EN-301-893 v1.5.1. Support for FCC and JP will be added gradually. To include the pattern detector, ath9k must be built with support for DFS certified config flag set (CONFIG_ATH9K_DFS_CERTIFIED).
