[Bug 1567744] Re: RTNETLINK answers: Numerical result out of range for alias interface from a usb NIC

[Mathieu Trudel-Lapierre]

Looks like at first glance ifupdown is confused by this naming format
together with the subif. I'll try to reproduce here, I do happen to have
a USB ethernet dongle that should show this problem.
