2013-08-05ath9k: Remove ath_ant_comb_update()Sujith Manoharan
During a HW reset, the diversity config is programmed in the set_board_values() eeprom callback, there is no need to do it again by calling ath_ant_comb_update(). Fixed antenna support is not fully handled for 1-stream cards, it can be done later. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

2013-08-05cw1200: Fix spurious BUG_ON() trigger when starting AP mode.Solomon Peachy
There's an underlying race condition with the unjoin_work() call that is sometimes triggered depending on scheduling order and the phase of the moon. This doesn't fix the race condition, but it does remove the ill-advised BUG_ON() call in an easily-recoverable situation. Signed-off-by: Solomon Peachy <pizza@shaftnet.org> Signed-off-by: John W.

2013-08-01iwl4965: better skb management in rx pathStanislaw Gruszka
4965 version of Eric patch "iwl3945: better skb management in rx path". It fixes several problems : 1) skb->truesize is underestimated. We really consume PAGE_SIZE bytes for a fragment, not the frame length. 2) 128 bytes of initial headroom is a bit low and forces reallocations. 3) We can avoid consuming a full page for small enough frames.

Whenever available, use cfg80211_scan_request to populates rates in outgoing probe request. This will help to advertise band specific rates and fix an issue where 11b rates were advertised in probe request going out on 11a band.

It has introduced by recent commit 6b41f941d7cd: "mwifiex: handle driver initialization error paths" which adds error path handling for mwifiex_fw_dpc(). release_firmware(adapter->*) is called for success as well as failure paths. In failure paths, adapter is already freed at this point. The issue is fixed by moving mwifiex_free_adapter() call.

2013-07-31mwifiex: check for bss_role instead of bss_mode for STA operationsAvinash Patil
This patch fixes an issue wherein association would fail on P2P interfaces. This happened because we are checking priv->mode against NL80211_IFTYPE_STATION. While this check is correct for infrastructure stations, it would fail P2P clients for which mode is NL80211_IFTYPE_P2P_CLIENT. Better check would be bss_role which has only 2 values: STA/AP.

2013-07-31iwlwifi: mvm: fix debugfs restart if fw_restart is disabledEran Harary
If fw_restart is disabled, using the fw_restart debugfs file will enable fw_restart and then send the failing command, but this still frequently fails restart because it resets fw_restart afterwards and is thus racy. Fix this by tracking fw_restart separately and allowing "always restart", "never restart" and "restart N times".
