[PATCH net-next 4/4] gve: Enable hw-gro by default if device supported

[Joshua Washington]

From: Ankit Garg <nktgrg@xxxxxxxxxx>

Change the driver's default behavior to enable hw-gro whenever supported
for device.

Performance observations:
- We observed ~10% improvement in RX single stream throughput across
  various MTU sizes.
- No change in TCP_RR/TCP_CRR latencies
