From 991ca269ed71b2b7aee27f5cb8bf64b689cc20bf Mon Sep 17 00:00:00 2001 From: Manish Chopra Date: Fri, 30 Aug 2013 13:51:16 -0400 Subject: [PATCH] qlcnic: Enhance PVID handling for 84xx adapters o PF driver should not indicate PVID configuration to VF driver. As adapter supports VLAN stripping, VF driver should stay agnostic to any PVID configuration. o Return "QLC_NO_VLAN_MODE(= 0)" to VFD when PVID is configured. VF driver should be in no VLAN configuration mode. Signed-off-by: Manish Chopra Signed-off-by: David S.
