Revision ad41faa88e39af451427c921a0f8b441e104b6fa authored by Nicolas Dichtel on 17 March 2015, 10:16:00 UTC, committed by David S. Miller on 17 March 2015, 18:58:39 UTC
The argument 'flags' was missing in ndo_bridge_setlink(). ndo_bridge_dellink() was missing. Fixes: 407af3299ef1 ("bridge: Add netlink interface to configure vlans on bridge ports") Fixes: add511b38266 ("bridge: add flags argument to ndo_bridge_setlink and ndo_bridge_dellink") CC: Vlad Yasevich <vyasevic@redhat.com> CC: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.
