           Summary: [networkd]: persistent mac setup: support devices on
                    the platform bus
        QA Contact: systemd-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: gdamjan at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: general
           Product: systemd

On the BeagleBoard-xM the ethernet interface is a usb device, using the
smsc95xx driver. As I've been told it's connected on the platform bus (see
udevadm output below). It doesn't have a hardware mac address, so networkd
should provide one. Unfortunately the default MACAddressPolicy=persistent
doesn't not configure the same mac address on each boot.

The distro is ArchLinuxArm (armv7l), systemd is 211.
