This patch series addresses several issues in the gve driver. All four of these
fixes were uncovered by running the net selftests.

The series includes the following changes:

- Patch 1 adds NULL pointer checks for the per-queue statistics code to
prevent crashes when the rings are queried while the link is down. This
was discovered by the drivers/net/stats.py selftest.
- Patch 2 fixes an issue where interface stats would go backwards when the
interface was brought down or its configuration was adjusted. This was
also discovered by the drivers/net/stats.py selftest.
- Patch 3 ensures the driver falls back to the default minimum ring size if
the corresponding device option values are exposed as 0. This prevents
userspace from configuring unexpectedly small ring sizes. This was
discovered by the drivers/net/ring_reconfig.py selftest.
- Patch 4 makes sure ethtool configuration modifications are done
synchronously before returning to the userspace. This was discovered by
the drivers/net/ping.py selftest.
