Subject: [dpdk-dev] [PATCH v2] net/ice: fix VLAN strip show in double VLAN mode
Date: Thu, 4 Feb 2021 10:03:33 +0800 [thread overview]
Message-ID: <20210204020333.6432-1-haiyue.wang@intel.com> (raw)
In-Reply-To: <20210203140303.65761-1-haiyue.wang@intel.com>
In double VLAN mode, the VLAN strip is applied on outer, since the VLAN
filter is outer; in single VLAN mode, the VLAN strip is applied on inner
for the VLAN filter is inner.
So it needs to adjust the strip setting according to current VLAN mode.
Fixes: 14e7a4b37b4f ("net/ice/base: support configuring device in double VLAN mode")
