From 278339a42a1bcef1fb448d275056d519307e6025 Mon Sep 17 00:00:00 2001 From: Jay Vosburgh Date: Fri, 28 Aug 2009 12:05:12 +0000 Subject: bonding: propogate vlan_features to bonding master Propogate the vlan_features of the slave devices to the bonding master device, using the same logic as for regular features. Tested by Or Gerlitz , who also removed the debug logic from the original test patch. Signed-off-by: Or Gerlitz Signed-off-by: Jay Vosburgh Signed-off-by: David S.
