bridge: Separate egress policy bitmap
Add an ability to configure a separate "untagged" egress
policy to the VLAN information of the bridge. This superseeds PVID
policy and makes PVID ingress-only. The policy is configured with a
new flag and is represented as a port bitmap per vlan. Egress frames
with a VLAN id in "untagged" policy bitmap would egress
the port without VLAN header.
