Sorry, I don't know how to reply to a thread so I guess this will do. Anyway, this port lacks the "-p" option, basically getting the original NIC MAC address. It seems it's a bit harder on BSD, since there's no ethtool, still ethtool -P doesn't work on my system, it shows me the cloned mac, not the original one. Anyway on BSD this can be achieved by doing two things: 1. using sysctl.XX.Y.nvm=1 (on newer bsd) or sysctl.XX.Y.debug=1 on older ones (thanks Jeremy Chadwick) to do an EEPROM dump, where XXX is interface name (e.g. em), and Y is the number(e.g. 0) 2. inspecting the output of dmesg, /var/log/messages specifically the first line, that is the original/permanent MAC of the NIC (tested also on VirtualBox) I am sure there is a better way to find this out, but syslog source needs to be inspected and such and it's gonna take some time, just wanted to point the author in the right direction.
