Subject: [dpdk-dev] [PATCH] net/i40e: fix to ensure vector mode is not used
Date: Tue, 11 Apr 2017 16:01:20 +0100 [thread overview]
Message-ID: <1491922880-18702-1-git-send-email-bernard.iremonger@intel.com> (raw)
In rx vector mode, the QinQ VLAN tag is not stripped.
When hw_vlan_extend is set for QinQ ensure that
rx vector mode is not selected.
Fixes: ca74903b75cf ("net/i40e: extract non-x86 specific code from vector driver")
