With the on-board ethernet of the SiS 630E chipset, when sip0 is first
ifconfiged, you must specify a media type. If not, ifconfig sip0 will list
the media as autoselect (none) and no network traffic will be seen in or
out (accompanied by sip0: device timeout errors). 
This has been seen with a 10baseT hub. It has not been tried with a
100baseTX switch/hub.
Create an ifconfig.sip0 file containing:
inet netmask

Reboot. Attempt to ping or tcpdump.
Now type:
ifconfig sip0 media 10baseT

You will now be able to ping or tcpdump, etc.
No fix known.

To work around, manually specify a media type, e.g. add the following to
your ifconfig.sip0 file:
media 10baseT
