-Subject: [PATCH] net: bridge: resolve VLAN tag actions in forwarding
- path for bridge devices
-
-Depending on the VLAN settings of the bridge and the port, the bridge can
-either add or remove a tag. When vlan filtering is enabled, the fdb lookup
-also needs to know the VLAN tag/proto for the destination address
-To provide this, keep track of the stack of VLAN tags for the path in the
-lookup context
