From f60c3704e87d39356d00c71bf51e55c2c55ad4f5 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Fri, 16 May 2014 17:20:39 -0400 Subject: [PATCH] bonding: Fix alb mode to only use first level vlans. ALB/TLB learning packets use all vlans configured on top of the bond. This ends up being incorrect if we have a stack of vlans on top of the bond. ALB/TLB should only use first level/outer most vlans in its announcements. Signed-off-by: Vlad Yasevich Signed-off-by: David S.
