From 6bbac866ce2e39d2f059240409f4018a153e1a1a Mon Sep 17 00:00:00 2001 From: Greg Rose Date: Thu, 28 Nov 2013 06:42:40 +0000 Subject: [PATCH] i40e: Stop accepting any VLAN tag on VLAN 0 filter set When the 8021q driver is loaded it sets VLAN 0 filters on all devices. This does not mean that any VLAN tagged packet should be accepted. Instead accept only VLAN 0 tagged packets so that upper layers can interpret the priority bits.
