Merge tag 'mac80211-next-for-net-next-2019-11-08' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
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()
 * use DEFINE_DEBUGFS_ATTRIBUTE in hwsim
====================

 /**
+ * DOC: VLAN offload support for setting group keys and binding STAs to VLANs
+ *
+ * By setting @NL80211_EXT_FEATURE_VLAN_OFFLOAD flag drivers can indicate they
+ * support offloading VLAN functionality in a manner where the driver exposes a
+ * single netdev that uses VLAN tagged frames and separate VLAN-specific netdevs
+ * can then be added using RTM_NEWLINK/IFLA_VLAN_ID similarly to the Ethernet
+ * case. Frames received from stations that are not assigned to any VLAN are
+ * delivered on the main netdev and frames to such stations can be sent through
+ * that main netdev.
+ *
+ * %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.
