* ath9k: use consistent value for REDUCE_SCALED_POWER_BY_THREE_CHAINGabor Juhos2012-04-16
| | | | | | | | | | | | | | | | | 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>

* ath9k_hw: Remove BTCOEX initvalsSujith Manoharan2012-04-13
| | | | | | | | | | | | | | | | | 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>

| * ath6kl: Fix 4-way handshake failure in AP and P2P GO modeVasanthakumar Thiagarajan2012-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | RSN capability field of RSN IE which is generated (which is what really advertised in beacon/probe response) differs from the one generated in wpa_supplicant. This inconsistency in rsn IE results in 4-way handshake failure. To fix this, configure rsn capability used in wpa_supplicant in firmware using a new wmi command, WMI_SET_IE_CMDID.

| | | | | | | | | | | | | | | | | | | | | | | | | | Using interface 0 for p2p causes target assert. This is because interface 0 is always initialized to non-p2p operations. Fix this issue by initializing all the interfaces for p2p when fw is capable of dynamic interface switching. When fw is not capable of dynamic switching, make sure p2p is not brought up on interface which is not initialized for this purpose.

| * ath6kl: Store scan request info in-advance before sending SCAN requestRaja Mani2012-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current code, Scan request info is recorded in vif->scan_req after sending SCAN request to the firmware in ath6kl_cfg80211_scan(). In some corner cases, firmware sends SCAN_COMPLETE event immediately when it receives SCAN request, which internally executes scan complete event handler ath6kl_cfg80211_scan_complete_event() first. So, Scan completion handler will a get a chance to executed even before storing scan request info in ath6kl_cfg80211_scan(). Scan completion handler never report SCAN_COMPLETE event to cfg80211 if scan request info(vif->scan_req) is NULL. This leads to scan failure issue ("Device or resource busy error") during next SCAN request from the user space. This patch ensures that scan request info is stored before sending SCAN request.

| * | ath6kl: handle probe response from P2P device in P2P GO modeAarthi Thiruvengadam2012-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the device is in P2P GO mode and in listen state, the correct behavior is to see two different probe response frames - one from P2P device and the other from GO. wpa_supplicant uses the same mechanism to send the frame in both cases (ath6kl_mgmt_tx). For GO probe response, ath6kl needs to call ath6kl_send_go_probe_resp (this will add only WSC/P2P IEs and the rest of the IEs are filled in by the firmware). That was done based on the nw_type == AP_NETWORK which would work if P2P Device role were in a separate netdev. When P2P Device and GO use the same netdev, ath6kl needs to use the special GO probe response case only if SSID is longer than P2P wildcard SSID.
