2014-02-20mac80211: allow driver to return error from sched_scan_stopJohannes Berg
In order to solve races with sched_scan_stop, it is necessary for the driver to be able to return an error to propagate that to cfg80211 so it doesn't send an event. Reviewed-by: Alexander Bondar <alexander.bondar@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2014-02-13wlcore: enable beacon filtering only after receiving a beaconEliad Peller
Enabling beacon filtering before receving a beacon might result in not having a beacon at all for the current connected AP, which prevents the station from entering power-save. Replace the current approach (of starting beacon filtering on init) and configure beacon filering only after bss_conf->dtimper is set (which means mac80211 already parsed a beacon).

2014-02-13wlcore: consider multiple APs when checking active_link_countEliad Peller

2014-02-13wlcore: don't handle unsetting of default wep keyEliad Peller
mac80211 unsets the default wep key on disassoc. The fw doesn't support this notification, so simply ignore it. The actual flow actually triggers fw recovery in some cases, as mac80211 unsets the default key only after disassoc, when wlvif->sta.hlid, resulting in invalid hlid being passed to the fw.

Bump the min wl18xx fw version to 8.8.0.0.13 This fw is not backward compatible with older firmware (due to api changes), so use bump the firmware name as well.

Each hw supports a different iface combinations. Define the supported combinations in each driver, and save it in wl->iface_combinations. Since each driver defines its own combinations now, it can also define its max supported channels, so we no longer need to save and set it explicitly in wlcore.

2014-02-13wlcore/wl12xx/wl18xx: configure num_links per-hwEliad Peller
Upcoming fw versions will have different max links support (according to the hw). Get ready for it by configuring wl->num_links per-hw, instead of using the const WL12XX_MAX_LINKS. However, continue using WLCORE_MAX_LINKS in order to simplify structs declarations (we use it in multiple bitmaps, and converting them to dynamic arrays is just cumbersome).

2014-02-13wlcore/wl12xx/wl18xx: simplify fw_status handlingEliad Peller
Instead of splitting the fw_status into 2 and using some complex calculations, read the fw status and let each low-level driver (wl12xx/wl18xx) convert it into a common struct. This is required for the upcoming fw api changes, which break the current logic anyway. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-02-13wlcore: AP: don't start mac80211 PS on non-peer HLIDsArik Nemtsov
It seems the wl18xx FW sometimes sends spurious changes on the PSM state of the broadcast HLID. This causes us to search for a station on a non-peer link and fail, causing warnings in our log.

2014-02-13wlcore: cancel Tx watchdog on suspend and rearm on first Tx afterArik Nemtsov
Sometimes a tx_flush during suspend fails, but the FW manages to flush out the packets during the time when the host is supsended. Cancel the Tx-watchdog on suspend to not cause a spurious recovery on resume for that case. Set a flag to reinit the watchdog on the first Tx after resume, so we'll still recover if the FW is not empty and there's indeed a problem.

2014-01-09wl1251: fix scan behaviour while not associatedDavid Gnedt
With a dissasociated card I often encoutered very long scan delays. My guess is that it has something to do with the cards DTIM handling and another firmware bug mentioned in the TI WLAN driver, which is described as the card may never end scanning if the channel is overloaded because it can't send probe requests. I think the firmware somehow also tries to receive DTIM messages when the BSSID is not set. Therefore most of the time it waits for DTIM messages and can't do scanning work. Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY bit for scans in disassociated state.
