Well you pushed me in the right direction to solve this.
Looking over the man pages for ifconfig and rc.conf, here is what I did.
1. Figure out what media options are available for the card
$ ifconfig -m fxp0
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
capability list:
=8<VLAN_MTU>
inet 192.168.0.16 netmask 0xffffff00 broadcast 192.168.0.255
ether 00:80:29:65:e2:96
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
supported media:
media autoselect
media 100baseTX mediaopt full-duplex
media 100baseTX
media 10baseT/UTP mediaopt full-duplex
media 10baseT/UTP
media 100baseTX mediaopt hw-loopback
2. According to the rc.conf man page, I added a file /etc/start_if.fxp0
with ->
ifconfig fxp0 media 100baseTX mediaopt full-duplex
To manually set media and media options at bootup.
Thats it. I rebooted, and the network is available immediately at bootup,
instead of waiting a few seconds to auto configure.
Thanks
