From 867a59436fc35593ae0e0efcd56cc6d2f8506586 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Wed, 5 Jun 2013 10:08:01 -0400 Subject: bridge: Add a flag to control unicast packet flood. Add a flag to control flood of unicast traffic. By default, flood is on and the bridge will flood unicast traffic if it doesn't know the destination. When the flag is turned off, unicast traffic without an FDB will not be forwarded to the specified port. Signed-off-by: Vlad Yasevich Reviewed-by: Michael S. Tsirkin Signed-off-by: David S.
