To support stations in power saving mode, AP should notify stations that there are frames buffered at the AP via TIM during beacons. Driver used to transmit identical beacons that were downloaded to hardware during the initiation phase. This beacon will become obsolete over time. If the beacon does not contain sufficient information, station would not be able to percept that there is data to receive. Hence it won't wake up and start the PS-poll procedure, this could lead to timeout and/or lost data segments. In order to resolve this issue, driver will now download beacon to hardware whenever the content is updated. Enable hardware to update dtim_count for more efficiency, this reduces the overhead of downloading beacon at every beacon interval since most of the time only the dtim_count needs to be updated. Change queue mapping for broadcast/multicast frames to high queue, so these frames can be prioritized and sent when dtim_count is zero. Signed-off-by:

Currently in mac80211 each STA object is represented using sta_info datastructure with the associated STA specific information and drivers access ieee80211_sta part of it. With MLO (Multi Link Operation) support being added in 802.11be standard, though the association is logically with a single Multi Link capable STA, at the physical level communication can happen via different advertised links (uniquely identified by Channel, operating class, BSSID) and hence the need to handle multiple link STA parameters within a composite sta_info object called the MLD STA. The different link STA part of MLD STA are identified using the link address which can be same or different as the MLD STA address and unique link id based on the link vif. To support extension of such a model, the sta_info datastructure is modified to hold multiple link STA objects with link specific params currently within sta_info moved to this new structure. Similarly this is done for ieee80211_sta as well which will be accessed within mac80211 as well as by drivers, hence trivial driver changes are expected to support this. For current non MLO supported drivers, only one link STA is present and link information is accessed via 'deflink' member. For MLO drivers, we still need to define the APIs etc. to get the correct link ID and access the correct part of the station info. Currently in mac80211, all link STA info are accessed directly via deflink. These will be updated to access via link pointers indexed by link id with MLO support patches, with link id being 0 for non MLO supported cases. Except for couple of macro related changes, below spatch takes care of updating mac80211 and driver code to access to the link STA info via deflink. @ieee80211_sta@ struct ieee80211_sta *s; struct sta_info *si; identifier var = {supp_rates, ht_cap, vht_cap, he_cap, he_6ghz_capa, eht_cap, rx_nss, bandwidth, txpwr}; @@ ( s-> - var + deflink.var | si->sta. - var + deflink.var ) @sta_info@ struct sta_info *si; identifier var = {gtk, pcpu_rx_stats, rx_stats, rx_stats_avg, status_stats, tx_stats, cur_max_bandwidth}; @@ ( si-> - var + deflink.var ) Signed-off-by:Sriram R <quic_srirrama@quicinc.com> Link: https://lore.kernel.org/r/1649086883-13246-1-git-send-email-quic_srirrama@quicinc.com [remove MLO-drivers notes from commit message, not clear yet; run spatch] Signed-off-by:

RTL8188CUS/RTL8192CU(gen1) don't support rate adaptive report hence no real txrate info can be retrieved. The vendor driver reports the highest rate in HT capabilities from the IEs to avoid empty txrate. This commit initiates the txrate information with the highest supported rate negotiated with AP. The gen2 chip keeps update the txrate from the rate adaptive reports, and gen1 chips at least have non-NULL txrate after associated. Signed-off-by:

To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1]. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.

Keeping the power to the SDIO card during system wide suspend, consumes energy. Especially on battery driven embedded systems, this can be a problem. Therefore, let's change the behaviour into allowing the SDIO card to be powered off, unless WOWL is supported and enabled. Note that, the downside from this change, is that during system resume the SDIO card needs to be re-initialized and the FW must be re-programmed. Even if this may take some time to complete, it should we worth it, rather than draining the battery. Signed-off-by:

cfg80211_ch_switch_notify uses ASSERT_WDEV_LOCK to assert that net_device->ieee80211_ptr->mtx (which is the same as priv->wdev.mtx) is held during the function's execution. mwifiex_dfs_chan_sw_work_queue is one of its callers, which does not hold that lock, therefore violating the assertion. Add a lock around the call. Disclaimer: I am currently working on a static analyser to detect missing locks. This was a reported case. I manually verified the report by looking at the code, so that I do not send wrong information or patches. After concluding that this seems to be a true positive, I created this patch. However, as I do not in fact have this particular hardware, I was unable to test it. Reviewed-by:
