Help with slip driver/need docs on network interface

[Brian Litzinger]

I'm working on a slip driver for System V.3.2 on a 386 PC.

I understand the serial port side, and the streams sides, of
some of the slip sources I've gotten for SunOS.

However, I am sorely lacking in understanding of the network
side of the interface.  My lack of understanding usually comes
from a lack of documentation, so a pointer to the right
documentation might be all I need.

Basically, I've noted the use of a function called 'if_attach()'
for which I have no documentation and I'm guessing in some
way establishes a connection to some network service.

Thanks in advance for any help.
