Okay, but realize this is a potentially dangerous operation.  Read the 
man page for patch(1) and the Handbook section on kernel configuration. 
Also, that patch is from a user and may not be of the same quality as if 
it were officially part of the FreeBSD source tree.

That said, download the patch.  It's called patch1.diff.

The first three lines show which file will be patched: 
sys/dev/bge/if_bgereg.h

On a normal FreeBSD system, system source file paths are relative to 
/usr/src.  So, as root:

cd /usr/src
patch < patch1.diff

You should see messages about patch hunks succeeding.  If there were no 
errors, you can build from the now-patched source.  This patch is to an 
Ethernet driver, so you probably only need to rebuild the kernel.  See 
the Handbook for custom kernel building and installing:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html

If you don't have a custom kernel, you don't need the KERNCONF= entries, 
or can use KERNCONF=GENERIC.

Finally, reboot and hope it works.
