I don't think its a good idea to selectively update random files of the 
network stack core.

Partial updates make it harder and harder to do a major update. I did 
this for complete subsystems like SDCard/MMC/USB, however, doing this 
for individual files is really a problem if want to update. The blocking 
point for an easy update to FreeBSD 10 or 11 are the user space command 
line programs like ifconfig and route. We need a better general approach 
to deal with user space programs. We may have time to do an update later 
this year.
