Public bug reported:

The GCE internal team responsible for gVNIC would like to have driver
updates backported for both Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.


[Impact]
Missing functionality from the Google gvnic driver


[Test Plan]
Confirm that gvnic module still loads and operates the gvnic driver. More extensive testing done by the gvnic developers at GCE


[Regression potential]
Possible regression in gvnic behaviour or functionality. Changes are confined to the gvnic driver code so regression potential is limited to gvnic only.


List of changes:
