The usual suffixes K, M, G are supported and are understood
to the base of 1024. For "tun" or "tap" devices, MTUBytes=
setting is not currently supported in [NetDev] section.
Please specify it in [Link] section of corresponding
systemd.network(5) files.
MACAddress=
The MAC address to use for the device. For "tun" or "tap"
