From 537f7f8494be4219eb0ef47121ea16a6f9f0f49e Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 25 Jun 2013 09:34:36 -0700 Subject: bridge: check for zero ether address in fdb add The check for all-zero ether address was removed from rtnetlink core, since Vxlan uses all-zero ether address to signify default address. Need to add check back in for bridge.
