From 407af3299ef1ac7e87ce3fb530e32a009d1a9efd Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Wed, 13 Feb 2013 12:00:12 +0000 Subject: bridge: Add netlink interface to configure vlans on bridge ports Add a netlink interface to add and remove vlan configuration on bridge port. The interface uses the RTM_SETLINK message and encodes the vlan configuration inside the IFLA_AF_SPEC. It is possble to include multiple vlans to either add or remove in a single message.

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. Signed-off-by: Vlad Yasevich Signed-off-by: David S.
