TCP/IP, not datakit.
The V8 manual contains internet(3), tcp(3), and udp(3). In the copy I have these are
dated 8/7/85. Down in the kernel in /usr/sys/inet the earliest files appear to be dated
3/22/85. I'm going to do a comparison with the 4.1cBSD TCP/IP stuff because a casual
glance reveals some overlap.

All of the files that have timestamps at the top list 83/07/29, except ip_input.c which
has 83/08/16 instead. The V8 version has _device (device driver) and _ld (line
discipline) components that the 4.1cBSD code does not have. Many other files have analogs
between the two. The byte ordering subroutines have been copied into a file, goo.s, from
their home in 4.1cBSD in the C library (/usr/src/lib/libc/net/misc). When this work
originated someone else would need to answer, but looks like it was as Warner described,
modified 4.xBSD TCP/IP.
