All network drivers are part of the kernel sources. You should have
them in your /usr/src/sys directory.
Having said that, the networking stack is a large piece of software,
with many parts and interactions between them. If you are planning to
get into that sort of development, you should probably consider reading
a _book_ about how things work.
Two excellent books about drivers and networking are:
"FreeBSD Device Drivers"
by Joseph Kong (Stark Press)
"The Design and Implementation of the FreeBSD Operating System"
by Marshall Kirk Mc Kusick & George V. Neville-Neil
(Addison-Wesley)
