nameif [-c configfile] [-s]
nameif renames network interfaces based on mac addresses. When no arguments are given /etc/mactab is read. Each line of it contains an interface name and a Ethernet MAC address. Comments are allowed starting with #. Otherwise the interfaces specified on the command line are processed. nameif looks for the interface with the given MAC address and renames it to the name given.
When the -s argument is given all error messages go to the syslog.
When the -c argument is given with a file name that file is read instead of /etc/mactab.
nameif should be run before the interface is up, otherwise it'll fail.
Only works for Ethernet currently.
