From 1414abea048e0835c43600d62808ed8163897227 Mon Sep 17 00:00:00 2001 From: Sucheta Chakraborty Date: Fri, 10 Jan 2014 11:48:52 -0500 Subject: [PATCH] qlcnic: Restrict VF from configuring any VLAN mode. o Adapter should allow vlan traffic only for vlans configured on a VF. On configuring any vlan mode from VF, adapter will allow any vlan traffic to pass for that VF. Do not allow VF to configure this mode. Signed-off-by: Sucheta Chakraborty Signed-off-by: David S.
