From 7677fc965fba41d1386fa3b76a1f00303f02bb2d Mon Sep 17 00:00:00 2001 From: Rony Efraim Date: Wed, 8 May 2013 22:22:35 +0000 Subject: net/mlx4: Strengthen VLAN tags/priorities enforcement in VST mode Make sure that the following steps are taken: - drop packets sent by the VF with vlan tag - block packets with vlan tag which are steered to the VF - drop/block tagged packets when the policy is priority-tagged - make sure VLAN stripping for received packets is set - make sure force UP bit for the VF QP is set Use enum values for all the above instead of numerical bit offsets.
