Subject: [patch net-next v3 16/17] bridge: add brport flags to dflt bridge_getlink
From: Scott Feldman <sfeldma@...il.com>
To allow brport device to return current brport flags set on port. Add
returned flags to nested IFLA_PROTINFO netlink msg built in dflt getlink.
With this change, netlink msg returned for bridge_getlink contains the port's
offloaded flag settings (the port's SELF settings).
