How do I Remove the Sl0 Port?

[Dave Bacon <dbacon@mail.owls.lib.wi.us>]

Every time I restart my Debian Linux Server, ifconfig reports an "Sl0"
(es, el, zero) port that is conflicting with "eth0".  The port "eth0
will not communicate with our Internet connection until I run "ifconfig
Sl0 down" which temporarily removes "Sl0" from the ifconfig listing.

Where, or how, do I tell my Debian Linux server not to bring up the
"Sl0" port every time I reboot the system?

Thank you in advance for any advise you can send my way.
