[dpdk-dev] [PATCH] net/i40e: fix to ensure vector mode is not used

[Bernard Iremonger]

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")
