[net-next 13/15] i40e: Enable Geneve offload for FW API ver > 1.4 for XL710/X710 devices

[Jeff Kirsher]

From: Anjali Singhai <anjali.sing...@intel.com>

This patch makes sure we check the GENEVE offload capable flag before
we attempt offload.
It also enables the Capability for XL710/X710 devices with FW API
version higher than 1.4
