====================
selftests: drv-net: gro: enable HW GRO and LRO testing

Add support for running our existing GRO test against HW GRO
and LRO implementation. The first 3 patches are just ksft lib
nice-to-haves, and patch 4 cleans up the existing gro Python.

Patches 5 and 6 are of most practical interest. The support
reconfiguring the NIC to disable SW GRO and enable HW GRO and LRO.
Additionally last patch breaks up the existing GRO cases to
track HW compliance at finer granularity.
