If the DSL modem is running in full duplex mode and the card in your
machine has auto-negotiated to half-duplex, things go to hell quickly.

Auto-negotiation sucks anyway.  It works about as well as Plug & Play.

ifconfig xl0 media 10BaseT mediaopt full-duplex

Or hell, try

ifconfig xl0 media 100BaseTX mediaopt full-duplex

Run "netstat -I xl0 -i 1" and watch for collisions.
