These rates are treated the same as 160 MHz in the spec, so it makes no sense to distinguish them. As no driver uses them yet, this is also not a problem, just remove them. In the userspace API the field remains reserved to preserve API and ABI. Signed-off-by:

When a system contains only self-managed regulatory devices all hints from the regulatory core are ignored. Stop hint processing early in this case. These systems usually don't have CRDA deployed, which results in endless (irrelevent) logs of the form: cfg80211: Calling CRDA to update world regulatory domain Make sure there's at least one self-managed device before discarding a hint, in order to prevent initial hints from disappearing on CRDA managed systems.

local->radar_detect_enabled should tell whether radar_detect is enabled on any interface belonging to local. However, it's not getting updated correctly in many cases (actually, when testing with hwsim it's never been set, even when the dfs master is beaconing). Instead of handling all the corner cases (e.g. channel switch), simply check whether radar detection is enabled only when needed, instead of caching the result. Signed-off-by:

The function adding the supported channels IE during a TDLS connection had several issues: 1. If the entire subband is usable, the function exitted the loop without adding it 2. The function only checked chandef_usable, ignoring flags like RADAR which would prevent TDLS off-channel communcation. 3. HT20 was explicitly required in the chandef, while not a requirement for TDLS off-channel. Signed-off-by:

When roaming / suspending, it makes no sense to wait until the transmit queues of the device are empty. In extreme condition they can be starved (VO saturating the air), but even in regular cases, it is pointless to delay the roaming because the low level driver is trying to send packets to an AP which is far away. We'd rather drop these packets and let TCP retransmit if needed. This will allow to speed up the roaming. For suspend, the explanation is even more trivial. Signed-off-by:

When a station disconnects with frames still pending, we clear the TIM bit, but too late - it's only cleared when the station is already removed from the driver, and thus the driver can get confused (and hwsim will loudly complain.) Fix this by clearing the TIM bit earlier, when the station has been unlinked but not removed from the driver yet. To do this, refactor the TIM recalculation to in that case ignore traffic and simply assume no pending traffic - this is correct for the disconnected station even though the frames haven't been freed yet at that point. This patch isn't needed for current drivers though as they don't check the station argument to the set_tim() operation and thus don't really run into the possible confusion. Reported-by:

Implement the new counters cfg80211 can now advertise to userspace. The TX code is in the sequence number handler, which is a bit odd, but that place already knows the TID and frame type, so it was easiest and least impact there. Signed-off-by:

The base for the current statistics is pretty mixed up, support exporting RX/TX statistics for MSDUs per TID. This (currently) covers received MSDUs, transmitted MSDUs and retries/failures thereof. Doing it per TID for MSDUs makes more sense than say only per AC because it's symmetric - we could export per-AC statistics for all frames (which AC we used for transmission can be determined also for management frames) but per TID is better and usually data frames are really the ones we care about. Also, on RX we can't determine the AC - but we do know the TID for any QoS MPDU we received. Signed-off-by:

This is really just duplicating the list of information that's already available in the nl80211 attribute, so remove the list. Two small changes are needed: * remove STATION_INFO_ASSOC_REQ_IES complete, but the length (assoc_req_ies_len) can be used instead * add NL80211_STA_INFO_RX_DROP_MISC which exists internally but not in nl80211 yet This gets rid of the duplicate maintenance of the two lists.

In many cases, drivers can filter things like beacons that will skew statistics reported by mac80211. To get correct statistics in these cases, call drivers to obtain statistics and let them override all values, filling values from mac80211 if the driver didn't provide them. Not all of them make sense for the driver to fill, so some are still always done by mac80211. Note that this doesn't currently allow a driver to say "I know this value is wrong, don't report it at all", or to sum it up with a mac80211 value (as could be useful for "dropped misc"), that can be added if it turns out to be needed. This also gets rid of the get_rssi() method as is can now be implemented using sta_statistics(). Signed-off-by:

When a station is removed, its statistics may be interesting to userspace, for example for further aggregation of statistics of all stations that ever connected to an AP. Introduce a new cfg80211_del_sta_sinfo() function (and make the cfg80211_del_sta() a static inline calling it) to allow passing a struct station_info along with this, and send the data in the nl80211 event message.

When hw acceleration is enabled, the GENERATE_IV or PUT_IV_SPACE flags only require headroom space. Therefore, the tailroom-needed counter can safely be decremented for most drivers. The older incarnation of this patch (ca34e3b5) assumed that the above holds true for all drivers. As reported by Christopher Chavez and researched by Christian Lamparter and Larry Finger, this isn't a valid assumption for p54 and cw1200. Drivers that still require tailroom for ICV/MIC even when HW encryption is enabled can use IEEE80211_KEY_FLAG_RESERVE_TAILROOM to indicate it. Signed-off-by:

This reverts commit ca34e3b5. It turns out that the p54 and cw2100 drivers assume that there's tailroom even when they don't say they really need it. However, there's currently no way for them to explicitly say they do need it, so for now revert this. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=90331.

dot11MulticastTransmittedFrameCount should be updated according to the DA, which might be different from A1. Checking A1 results in the counter being 0 in case of station, as to-DS data frames use A1 for the BSSID. This behaviour is defined in state machines, specifically in the sta_tx_dcf_3.1d(10) description of 802.11-2012. Signed-off-by:
