 Hello,
 FWIW, I tested this patch on FreeBSD 8.1-stable:
 root@kg-omni1# uname -a
 FreeBSD kg-omni1.kg4.no 8.1-STABLE FreeBSD 8.1-STABLE #0: Sun Oct 17 12:35:38 CEST 2010     root@kg-i82.kg4.no:/usr/obj/usr/src/sys/GENERIC  i386
 
 It works flawlessly.
 Without the patch, dhclient would not exit, resulting in no new lease being aquired when the link goes down and up again. 
 With the patch, dhclient exits and gets started when the link comes up again. From /var/log/messages:
 Jul 12 11:37:07 kg-omni1 dhclient[30335]: Link xl0 is down, dhclient exiting
 Jul 12 11:37:07 kg-omni1 kernel: xl0: link state changed to DOWN
 Jul 12 11:37:07 kg-omni1 dhclient[30322]: connection closed

 Jul 12 11:37:20 kg-omni1 dhclient: New Broadcast Address (xl0): 255.255.255.255
