From 58945e1bd6e7ed8d3637c655ebdfdc34fa996456 Mon Sep 17 00:00:00 2001 From: Manish Chopra Date: Fri, 16 Aug 2013 19:07:14 -0400 Subject: [PATCH] qlcnic: Add PVID support for 84xx adapters o 84xx adapters support VLAN stripping for PVID. Packets don't have VLAN tag inserted in case of PVID. So packet should follow non vlan path. o Use capability bit to set PVID mode.
