I have been seeing this problem for over a year, and have had the same
problems you have with DoS attacks saturating the CPUs on our routers.

Have a look at current kernels and see if they solve your problem.
They undoubtedly should, and I consider this issue resolved.

The hash collision problem appears to be resolved, but not the more
general performance issues.  Or are there any kernels without a
routing cache?
