From f3a6ddf15209cfad90b83e04168f42a5d9c8cc17 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Fri, 16 May 2014 09:59:18 -0400 Subject: [PATCH] bridge: Introduce BR_PROMISC flag Introduce a BR_PROMISC per-port flag that will help us track if the current port is supposed to be in promiscuous mode or not. For now, always start in promiscuous mode. Acked-by: Michael S. Tsirkin Signed-off-by: Vlad Yasevich Signed-off-by: David S.
