Subject: [PATCH net-next 0/5] gve: enable ring size changes

This series enables support to change ring size via ethtool
in gve.

The first three patches deal with some clean up, setting
default values for the ring sizes and related fields. The
last two patches enable ring size changes.

Harshitha Ramamurthy (5):
  gve: simplify setting decriptor count defaults
  gve: make the completion and buffer ring size equal for DQO
  gve: set page count for RX QPL for GQI and DQO queue formats
  gve: add support to read ring size ranges from the device
  gve: add support to change ring size via ethtool
