kernel relink ip address change

For efficiency reasons, SCO put the slink module (which builds the TCP/IP STREAMS stack) into the kernel. This can be disabled using ksl.disable in the bootstring. Of course, if you want, you can use ifconfig to change addresses, it just won't be permanent. Personally, I thought this was a stupid decision, myself.
