gve: Deprecate adminq_pfn for pci revision 0x1. adminq_pfn assumes a page size of 4k, causing this mechanism to break in kernels compiled with different page sizes. A new PCI device revision was needed for the device to be able to communicate with the driver how to set up the admin queue prior to having access to the admin queue.

gve: Add Gvnic stats AQ command and ethtool show/set-priv-flags. This adds functionality to report driver stats to Hypervisor. (Users may want to turn this feature off as a matter of privacy so a "report-stats" flag is added as an ethtool priv option. It is also disabled by default.) The hypervisor would trigger a stats report in case "too many" packets dropped; the stats would be useful in debugging stuck queues. A "stats_report_trigger_cnt" stat is added to count the number of times the hypervisor attempts to trigger stats report. A timer is also added so that when report-stats is enabled, stat are updated once every 20 seconds.
