[PATCH 1/1] net/gve: update base code for DQO

[Guo, Junfeng]

Hi Ferruh & Bruce,

This patch contains few lines change for the MIT licensed gve base code.
Note that there is no new files added, just some minor code update.

Do we need to ask for special approval from the Tech Board for this?
Please help give some advice and also help review this patch. Thanks!

BTW, Google will also help replace all the base code under MIT license
with the ones under BSD-3 license soon, which would make things more
easier.

Regards,
Junfeng
