[PATCH 1/3] bridge: handle process all link-local frames
From: Stephen Hemminger <hidden>
Date: 2008-06-17 16:52:55
Any frame addressed to link-local addresses should be processed by local receive path. The earlier code would process them only if STP was enabled. Since there are other frames like LACP for bonding, we should always process them. Signed-off-by: Stephen Hemminger <redacted>
