From 1960827570c7ed83fb0725debf856b06f46e1a77 Mon Sep 17 00:00:00 2001 From: Brett Creeley Date: Fri, 15 May 2020 17:42:13 -0700 Subject: [PATCH] ice: Don't allow VLAN stripping change when pvid set Currently, if the PVID is set in the VLAN handling section of the VSI context the driver still allows VLAN stripping to be enabled/disabled. VLAN stripping should only be modifiable when the PVID is not set. Fix this by preventing VLAN stripping modification when PVID is set.
