Hmm, I thought I tried that before, but using
MACAddress=fe:ed:fa:ce:be:ef seems to work now. Please note that the
Name= match is not documented in the systemd.link manpage.

MACAddressPolicy=persistent doesn't seem to have an effect on bridge
devices though (with systemd 212), but I don't rely on that anyways.
