NAME
       nameif - name network interfaces based on MAC addresses
SYNOPSIS
       nameif [-c configfile] [-s]
       nameif [-c configfile] [-s] {interface macaddress}
DESCRIPTION
       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.
NOTES
       nameif  should be run before the interface is up, otherwise it’ll fail.
FILES
       /etc/mactab
BUGS
       Only works for Ethernet currently.
