Different versions of gve kernel driver change a lot. So for reference, I think 
adding the version info for the base code makes sense. Just tell the following 
update people which version is used.

It's not just directly copy. Directly copy like gve_desc.h doesn't have Intel 
copyright.
But gve.h, in gve kernel driver, it has a lot of info dpdk doesn't need or dpdk 
has its own version like txq/rxq info.
I'm not sure the contribution is a lot or not. But I suppose this patchset is 
following the principle that if the code is changed, intel copy right is added, 
otherwise, only google's copyright.
