Basically you may have to save your old driver sources to safe
place. And download the three files above and copy them to
appropriate source directory and rebuild kernel/reboot.
For instance, after downloading,
Copy if_re.c to /usr/src/sys/dev/re/
Copy if_rl.c to /usr/src/sys/pci/
Copy if_rlreg.h to /usr/src/sys/pci/
And rebuild kernel.
Handbook may have instructions how to rebuild kernel.
Good luck.
