A Brief History of Linux Networking Kernel Development.
As with the rest of the Linux operating system and its numerous components
development of networking stack within Linux has been both a slow and
complex journey that has resembled that journey that has been faced by
people in the development of networking stacks of other operating systems
such as Microsoft Windows and Free BSD.

Developing a brand new kernel implementation of the tcp/ip protocol
stack that would perform as well as existing implementations was not
an easy task. The decision not to port one of the existing
implementations was made at a time when there was some uncertainty as
to whether the existing implementations may become encumbered by
restrictive copyrights because of the court case put by U.S.L. and
when there was a lot of fresh enthusiasm for doing it differently and
perhaps even better than had already been done.

As has been stated in the Linux Networking HOWTO
(http://tldp.org/HOWTO/NET3-4-HOWTO.html)
the actual implementation of the TCP/IP protocol stack was done
basically from scratch due to concerns with regards to copyright issues
as well as the possibilty that developers would be able to come up
with a protocol stack that was superior to existing protocol stacks.
