From eb7cfd8c9b6e28edf339b89bf19322c11514d286 Mon Sep 17 00:00:00 2001 From: Andrew Rybchenko Date: Wed, 15 Jun 2016 17:51:36 +0100 Subject: [PATCH] sfc: Disable VLAN filtering by default if not strictly required If should be done after net_dev->hw_features initialization, to keep the feature there to be able to enable it later using ethtool. VLAN filtering is enforced and fixed if vPort requires usage of VLAN filters to receive tagged traffic. Signed-off-by: Edward Cree Signed-off-by: David S.
