From 3ae412544cde6d987e0e48778bd87bc96a5749df Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Sun, 16 Dec 2007 13:35:51 -0800 Subject: [PATCH] [BRIDGE]: Assign random address. Assigning a valid random address to bridge device solves problems when bridge device is brought up before adding real device to bridge. When the first real device is added to the bridge, it's address will overide the bridges random address. Note: any device added to a bridge must already have a valid ethernet address. br_add_if -> br_fdb_insert -> fdb_insert -> is_valid_ether_addr Signed-off-by: Stephen Hemminger Signed-off-by: David S.
