Add gve, the driver for Google Virtual NIC (gVNIC)HEADmain
gVNIC is a virtual network interface designed specifically for Google Compute Engine (GCE). It is required to support per-VM Tier_1 networking performance, and for using certain VM shapes on GCE. The NIC supports TSO, Rx and Tx checksum offloads, and RSS. It does not currently do hardware LRO, and thus the software-LRO in the host is used instead. It also supports jumbo frames. For each queue, the driver negotiates a set of pages with the NIC to serve as a fixed bounce buffer, this precludes the use of iflib.
