My observation with the rl driver on FreeBSD 4.x is that it does not detect
properly that the network is running at 10baseT. You have to explicitely
tell it to use 10base/T (using ifconfig rl0 media 10baseT/UTP) for it to
work. Maybe this is something that is also broken for other drivers.
This is especially annoying when you use DHCP because then the setting will
be lost everytime DHCP feels like it needs to reconfigure the interface.
See the output of ifconfig: media: autoselect (none) ... where it should say
"media: autoselect (10baseT/UTP).
bash-2.04$ ifconfig -a
rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
atalk 9.50 range 0-65534 phase 2 broadcast 0.255
ether 00:50:ba:b0:96:d9
media: autoselect (none) status: active
supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback>
If somebody has any idea on how to fix this problem, I am more than willing
to lend a hand and spend time testing patches etc.
Patrick.
