What works for me, mentioned here
viewtopic.php?f=67&t=14576Create a /usr/lib/systemd/system/macspoof@.service with contents (change mac to whatever you want),
$this->bbcode_second_pass_code('', '
[Unit]
Description=MAC Address Change %I
Wants=network-pre.target
Before=network-pre.target
BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device
[Service]
Type=oneshot
ExecStart=/usr/bin/ip link set dev %i address FE:ED:DE:AD:BE:EF
ExecStart=/usr/bin/ip link set dev %i up
[Install]
WantedBy=multi-user.target
')
Finally, $sudo systemctl enable
macspoof@eth0.service and reboot.
