From 61c9ce86a6f5c3c2eb1dad89da0c758f586ffc3f Mon Sep 17 00:00:00 2001 From: Brett Creeley Date: Wed, 22 Jan 2020 07:21:27 -0800 Subject: [PATCH] ice: Fix Port VLAN priority bits Currently when configuring a port VLAN for a VF we are only shifting the QoS bits by 12. This is incorrect. Fix this by getting rid of the ICE specific VLAN defines and use the kernel VLAN defines instead. Also, don't assign a value to vlanprio until the VLAN ID and QoS parameters have been validated. Also, there are many places we do (le16_to_cpu(vsi->info.pvid) & VLAN_VID_MASK). Instead do (vf->port_vlan_info & VLAN_VID_MASK) because we always save what's stored in vsi->info.pvid to vf->port_vlan_info in the CPU's endianness.
