====================
Some relatively small changes:
 * typo fixes in docs
 * APIs for station separation using VLAN tags rather
   than separate wifi netdevs
 * some preparations for upcoming features (802.3 offload
   and airtime queue limits (AQL)
 * stack reduction in ieee80211_assoc_success()

cfg80211: VLAN offload support for set_key and set_sta_vlan 2019-11-08T10:19:19+00:00 Gurumoorthi Gnanasambandhan gguru@codeaurora.org 2019-10-31T21:46:40+00:00 14f34e36b36ceede9877ca422a62fcac17b52023 This provides an alternative mechanism for AP VLAN support where a single netdev is used with VLAN tagged frames instead of separate netdevs for each VLAN without tagged frames from the WLAN driver. By setting NL80211_EXT_FEATURE_VLAN_OFFLOAD flag the driver indicates support for a single netdev with VLAN tagged frames. Separate VLAN-specific netdevs can be added using RTM_NEWLINK/IFLA_VLAN_ID similarly to Ethernet. NL80211_CMD_NEW_KEY (for group keys), NL80211_CMD_NEW_STATION, and NL80211_CMD_SET_STATION will optionally specify vlan_id using NL80211_ATTR_VLAN_ID.

mac80211: fix scan when operating on DFS channels in ETSI domains 2019-10-07T20:10:50+00:00 Aaron Komisar aaron.komisar@tandemg.com 2019-10-02T13:59:07+00:00 dc0c18ed229cdcca283dd78fefa38273ec37a42c In non-ETSI regulatory domains scan is blocked when operating channel is a DFS channel. For ETSI, however, once DFS channel is marked as available after the CAC, this channel will remain available (for some time) even after leaving this channel. Therefore a scan can be done without any impact on the availability of the DFS channel as no new CAC is required after the scan. Enable scan in mac80211 in these cases.
