From 5d9a533bacff6fbaf711c92575f5f646c2c772f1 Mon Sep 17 00:00:00 2001 From: Pascal Bouchareine Date: Thu, 14 Jun 2012 02:18:18 +0000 Subject: [PATCH] ixgbevf: fix VF untagging when 802.1 prio is set We have had an issue when using ixgbe+ixgbevf and 802.1 VLAN tagging. When attaching a VLAN to a VF, frames with a 802.1q priority appeared untagged on the VF hence not reaching the VLAN, where frames with priority 0 where tagged as expected and seen by the VLAN device. This seems due to the way ixgbevf is looking up the full tag (prio+cfi+vlan) against the adapter active_vlans, as a condition to mark the skb tagged.
