These are changes by Kip to do TCP offload (181013, 181014).
Given that, I think the likeliest changes to cause this are the TCP offload
changes. Note that Kip later MFC'd this change which changed ARP stuff:
However, I would stary by narrowing it down to see if Kip's commits cause the
change.
As I dont have the skills to unwind Robert's patch, I have done the following
csup with date=2008.08.01.00.00.00
which shows the problem. I then manually grabbed the prior versions
of the above files

All is OK. So it looks like the above introduced the bug.
