* 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.
