Public bug reported:
Originally from https://bugs.debian.org/812575: Our current
/lib/systemd/network/90-mac-for-usb.link assigns MAC-based names to all
USB devices. However, this is wrong and pointless for locally
administered MAC addresses (with the second bit set to '1', see
https://en.wikipedia.org/wiki/MAC_address#Address_details).
The old 75-persistent-net generator had this rule:
ENV{MATCHADDR}=="?[2367abef]:*", ENV{MATCHADDR}=""
which ignored these devices. We need to adjust 90-mac-for-usb.link to do
the same, and only apply to universally administered MAC addresses (at
least until https://lists.ubuntu.com/archives/ubuntu-
devel/2016-April/039302.html gets concluded).
We should simply fall through the default policy of assigning location
based names. The kernel assigned ones have no meaning whatsoever, so
this at least provides name stability for use cases where you can rely
on plugging the device into the same port.
