From 8ac4307504bed19ce68b39bc2703975ee0b9ab81 Mon Sep 17 00:00:00 2001 From: Haiyue Wang Date: Thu, 4 Feb 2021 10:03:33 +0800 Subject: [PATCH] net/ice: fix VLAN strip for double VLAN VLAN strip was failing for double VLAN because of hardware configuration, resulting mbuf not having the vlan_tci information. Adjusted the strip setting according to current VLAN mode to fix the VLAN strip.
