Not sure I'm qualified to perform that level of surgery, but I'll take
a look at ipv4 and try to understand how that works.
In the meantime does it make sense to put a smaller bandaid in 3.8?
I'm pretty sure this is a regression (we never saw it with older
kernels), probably due to some part of the route cache improvements
you've been doing.
