We don't have to double check whether the parameters passed to cfg80211_can_use_iftype_chan() are correct. We should just make sure they *are* when we call this function.

docbook (or one of its friends) gets confused with semi-colons in the argument descriptions, causing it to think that the semi-colon is marking a new section in the description of addr_mask in wiphy struct.

2014-02-21cfg80211: regulatory: introduce NL80211_RRF_AUTO_BW rule flagJanusz Dziedzic4-43/+58
Introduce NL80211_RRF_AUTO_BW rule flag. If this flag set maximum available bandwidth should be calculated base on contiguous rules and wider channels will be allowed to cross multiple contiguous/overlapping frequency ranges. In case of old kernels maximum bandwidth from regulatory rule will be used, while there is no NL80211_RRF_AUTO_BW flag. This fixes the previous commit 9752482083066af7ac18a5ca376f ("cfg80211: regulatory introduce maximum bandwidth calculation") which was found to be a problem for userspace API compatibility.

2014-02-20mac80211: allow driver to return error from sched_scan_stopJohannes Berg5-10/+19
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>

2014-02-20cfg80211: Pass TDLS peer capability information in tdls_mgmtSunil Dutt Undekari7-13/+47
While framing the TDLS Setup Confirmation frame, the driver needs to know if the TDLS peer is VHT/HT/WMM capable and thus shall construct the VHT/HT operation / WMM parameter elements accordingly. Supplicant determines if the TDLS peer is VHT/HT/WMM capable based on the presence of the respective IEs in the received TDLS Setup Response frame. The host driver should not need to parse the received TDLS Response frame and thus, should be able to rely on the supplicant to indicate the capability of the peer through additional flags while transmitting the TDLS Setup Confirmation frame through tdls_mgmt operations.

2014-02-14wlcore: enable beacon filtering only after receiving a beaconEliad Peller3-3/+16
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).

2014-02-14wlcore: don't handle unsetting of default wep keyEliad Peller1-0/+4
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.

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.

2014-02-14wlcore/wl12xx/wl18xx: configure num_links per-hwEliad Peller11-30/+51
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).

2014-02-14wlcore/wl12xx/wl18xx: simplify fw_status handlingEliad Peller12-103/+277
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>
2014-02-14wlcore: AP: don't start mac80211 PS on non-peer HLIDsArik Nemtsov1-1/+5
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.

2014-02-14wlcore: cancel Tx watchdog on suspend and rearm on first Tx afterArik Nemtsov3-2/+21
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.

2014-02-14wlcore: memset wl->rx_filter_enabled to zero after recoveryNadim Zubidat3-4/+8
zero rx_filter_enabled array after recovery to avoid cases were the driver will keep trying to clear a filter which is not configured in FW. Such case will cause consecutive recoveries due to command execution failures. While on it, convert rx_filter_enabled to bitmap, to save some memory and make sparse happy (it doesn't like sizeof(bool array)).

2014-02-13mac80211: add NAPI support backJohannes Berg4-22/+31
NAPI was originally added to mac80211 a long time ago (by John in commit 4e6cbfd09c66 in July 2010), but then removed years later (by Stanislaw in commit 30c97120c6c7 in February 2013). No driver ever used it, so that was fine. Now I'm adding support for NAPI to our driver, so add some code to mac80211 again to support NAPI. John was originally wrapping some (but not nearly all NAPI-related functions), but that doesn't scale very well with the number of functions that are there, some of which are even only inlines. Thus, instead of doing that, let the drivers manage the NAPI struct, except for napi_add() which is needed so mac80211 knows how to call napi_gro_receive(). Also remove some no longer needed definitions that were left when NAPI support was removed.
