netdev-offload-dpdk: Fix for broken ethernet matching HWOL for XL710NIC.

Browse Source 
This patch introduces a temporary work around to fix
partial hardware offload for XL710 devices. Currently the incorrect
ethernet pattern is being set. This patch will be removed once
this issue is fixed within the i40e PMD.
