2015-01-27ath9k and ath9k_htc: rename variable "led_blink"Hong Xu
ath9k and ath9k_htc use the variable name "led_blink" to indicate whether the module parameter "blink" is on. This name is easy to conflict with other variables, and has caused a compiler error found by kbuild test bot. The compiler error is as following: drivers/net/wireless/ath/ath9k/ath9k_htc.o:(.data+0x47c): multiple definition of `led_blink' drivers/net/wireless/ath/ath9k/ath9k.o:(.bss+0x20): first defined here Fixes: 3a939a671225 ("ath9k_htc: Add a module parameter to disable blink") Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Hong Xu <hong@topbug.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2012-09-28ath9k: Fix BTCOEX weight initializationSujith Manoharan
The WLAN/BT weights have to set correctly before BTCOEX is initialized. Currently, this is not done for all chips in the AR9003 family. This patch fixes this issue by setting the weights in the init path. While at it, rename ar9462_wlan_weights to mci_wlan_weights since it is common to both AR9462 and AR9565.

2011-12-19ath9k_hw: make bluetooth coexistence support optional at compile timeFelix Fietkau
Many systems (e.g. embedded systems) do not have wifi modules connected to bluetooth modules, so bluetooth coexistence is irrelevant there. With the addition of MCI support, ath9k picked up quite a bit of extra code that can be compiled out this way. This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for querying the bluetooth coexistence scheme, allowing the compiler to eliminate code that uses it, with only very little use of #ifdef. On MIPS this reduces the total size for the modules by about 20k. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-04-13ath9k_htc: Drain pending TX frames properlySujith Manoharan
When doing a channel set or a reset operation the pending frames queued up for transmission have to be flushed and sent to mac80211. Fixing this has to be done in two separate steps: * Flush queued frames and kill the URB TX completion handler. * Complete all the frames that in the TX pending queue. This patch adds proper support for draining and all the callsites namely, channel change/reset/idle/stop are fixed. A separate queue is used for handling failed frames.

2011-04-13ath9k_htc: Fix TX queue managementSujith Manoharan

2011-04-13ath9k_htc: Queue WMI eventsSujith Manoharan
Use a queue to handle WMI events and schedule a tasklet to process the events. This fixes the race between the WMI event ISR and the SWBA tasklet when the arrival of WMI events in quick succession could overwrite the SWBA data before the tasklet from a previous iteration could have been scheduled. Also, drain the WMI queue properly. Signed-off-by: Sujith Manoharan <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
