From: Thomas Richter Date: Tue, 30 Jul 2013 06:16:41 +0000 (+0200) Subject: iproute vxlan add support for fdb replace command X-Git-Tag: v3.11.0~15 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5464049b4781eae2f664009a217fbcfd6a7b13c1;p=thirdparty%2Fiproute2.git iproute vxlan add support for fdb replace command Add support for the bridge fdb replace command to replace an existing entry in the vxlan device driver forwarding data base. The entry is identified with its unicast mac address and its corresponding remote destination information is updated. This is useful for virtual machine migration and replaces the bridge fdb del and bridge fdb add commands. It follows the same interface as ip neigh replace commands.
