We can also do away with vxlan_port and nge_port, now that we no
longer need to pass the port from NDO to workqueue.  We just need to
initialize the 2 firmware tunnel IDs to INVALID_HW_RING_ID before use
and after free.  But it is ok the way you have it too.

I like this v2 version better with the VXLAN and GENEVE types defined.

Thanks.
