In netdev_linux_get_status(), I don't understand why we want to return
vport_stats_error.  We know that we have driver info at that point, so
why not just return 0?  It would save a system call.

I understand why you don't call netdev_linux_get_drvinfo() from
netdev_internal_open(), because you told me, but it's not obvious from
the code.  I think that a comment is warranted.

Thanks,

Ben.
