Bug#768908: networkd: please support bridge mac cloning

[Christian Hofstaedtler]

Package: systemd
Version: 215-5+b1
Severity: wishlist

Dear systemd Maintainers,

while trying out networkd with a bridge setup, I've been unable to
find how to set a static MAC address for the setup bridge.

Ideally I'd like to just clone the MAC of the physical device, but
setting a static address using a string would do fine as well.

The typical use case for the cloning stuff is a bridge attached to
a single ethX device, and other devices joining the bridges that
are configured through libvirt or any other of virtualization tool.

Why is the MAC even important? Because desktops tend to use DHCP
and they may have "static" IP or other assignments that are bound
to the MAC address.

Thanks,
Christian
