Nitpicking ... at some point in time i40e_status should be removed plus
I40E_ERR_PARAM, I40E_SUCCESS, I40E_ERR_NO_MEMORY and the like, as we have
int and -EINVAL, 0, -ENOMEM for that. ;-)

+	return I40E_SUCCESS;

Their usage seems also to be mixed anyway: -ENOMEM vs. I40E_SUCCESS.

Probably the code could also be scanned to remove such checks as well ...
