From 14f34e36b36ceede9877ca422a62fcac17b52023 Mon Sep 17 00:00:00 2001 From: Gurumoorthi Gnanasambandhan Date: Thu, 31 Oct 2019 23:46:40 +0200 Subject: cfg80211: VLAN offload support for set_key and set_sta_vlan 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.
