Unfortunately, that won't work. /etc/rc.conf is part of a shell
script, and all of those variable=value lines within it are literally
assignments to shell variables. Thus all you're doing with those
lines is setting 'ifconfig_dcX' to the value "DHCP" and then
immediately resetting it to the value "media 100baseTX mediaopt
On recent FreeBSD 6.x you can just combine the lines:
ifconfig_dc0="DHCP media 100baseTX mediaopt full-duplex"
(I can't remember if that also works on 5.x -- you'll need to read
/etc/network.subr to find out).
In any case, and certainly for older FreeBSD versions you can always
create a /etc/start_if.dc0 script, which will be run immediately
before the ifconfig(8) command generated out of /etc/rc.conf. In your
case, the script should look like:
ifconfig dc0 media 100baseTX mediaopt full-duplex
but you can put any arbitrary commands in there that you want. Ditto
for the dc1 interface, except call the script /etc/start_if.dc1 (if
that isn't bleedingly obvious...) There are corresponding
/etc/stop_if.XXN scripts that can be created to do arbitrary stuff on
interface shutdown as well.
