    It isn't quite clear what you mean, but presuming you mean "make
    a change to the FreeBSD kernel that you use" then:

    1) First learn how to recompile your kernel.
       You can get details from the FreeBSD handbook
       (http://www.freebsd.org/handbook/).
    2) Look under /usr/src/sys for the kernel source code.
       The main bit is in /usr/src/sys/kern, networking
       lives under /usr/src/sys/net* and so on.
    3) Change the code you want and then recompie the kernel.
       Remember to keep an old kernel around incase you make
       a mistake.

            David.
