This is not a valid configuration. FreeBSD does not allow you to configure
multiple network interfaces onto the same logical network. You probably
want the 'alias' command to add the IPs to one physical interface. This is
addressed in the FAQ and Handbook, and the ifconfig(8) man page.

If you want to do trunking, that is another matter.

Also be careful with your media statements, particuarly with regard to
duplex.  You may need to specify the duplex type with mediaopt.
