[PATCH net-next 1/4] gve: Advertise NETIF_F_GRO_HW instead of NETIF_F_LRO

[Joshua Washington]

From: Ankit Garg <nktgrg@xxxxxxxxxx>

The device behind DQO format has always coalesced packets per stricter
hardware GRO spec even though it was being advertised as LRO.

Update advertised capability to match device behavior.
