Need to update index file (doc/guides/nics/index.rst) to make new 
gve.rst file visible. Did you test build and viewing the documentation?

Can you please add this patch as first patch with infrastructure files 
(like meson files, .map file etc..) and later update the .ini with each 
patch, as a patch introduces a feature update .ini to add that feature.

Can you please provide some references for the device? Official product 
link etc...

Instead of listing these files in the documentation, what do you think 
to place under a 'base' folder (drivers/net/gve/base/*) which will 
clarify that these are base code files.

Same comment as .ini file above. Let's build the features list gradually 
as code adds them, instead of adding it as batch at the end.
