Thanks for reviewing my patch, Helin and David.

I agree that it's subtle to ignore the error, and just log the
error. This is how ixgbevf behaves (refer to
ixgbevf_dev_configure), so I figured that i40evf should behave
analogous.

I'll submit a v2 of the patch that returns an EINVAL and logs the
failure.

Would it make sense to change the ixgbevf_dev_configure as well,
in a separate patch?

Noted. Will make sure to fix that for future revisions. Thanks!
