From: Ivan Vecera Date: Fri, 20 Jan 2017 17:12:17 +0000 (+0100) Subject: bridge: netlink: call br_changelink() during br_dev_newlink() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b6677449dff674cf5b81429b11d5c7f358852ef9;p=openwrt%2Fstaging%2Fblogic.git bridge: netlink: call br_changelink() during br_dev_newlink() 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: 133235161721 ("bridge: implement rtnl_link_ops->changelink") Signed-off-by: Ivan Vecera Reviewed-by: Jiri Pirko Signed-off-by: David S.
