bridge: netlink: call br_changelink() during br_dev_newlink()
Browse files Browse the repository at this point in the history
Any bridge options specified during link creation (e.g. ip link add)
are ignored as br_dev_newlink() does not process them.
Use br_changelink() to do it.

Fixes: 1332351 ("bridge: implement rtnl_link_ops->changelink")
