-Subject: [PATCH] netfilter: flowtable: rework ingress vlan matching
-
-When dealing with bridges with VLAN filtering and DSA/switchdev offload,
-the hardware could offload adding a VLAN tag configured in the bridge.
-Since there doesn't seem to be an easy way to detect that, this patch
-reworks the code to optionally match the last VLAN tag that would otherwise
-be inserted by the bridge.
-This matters when bypassing the bridge and attaching an ingress hook on
-a DSA port below it.

-Subject: [PATCH] netfilter: flowtable: handle bridge vlan filter offload
- tags from DSA/switchdev
-
-When a switchdev/DSA port is an untagged member of a bridge vlan, ingress
-packets could potentially be tagged with the id of the VLAN.
-When the VLAN port group has been uploaded to switchdev, report the bridge
-tag mode as DEV_PATH_BR_VLAN_UNTAG_HW instead of DEV_PATH_BR_VLAN_UNTAG
-and handle it in netfilter flow offloading by storing the tag in the tuple
-in_pvid field.
-This allows the ingress hook to detect the optional tag and remove it for
-software offload. This tag processing is for ingress only, egress needs to be
-fully untagged
