Is there any danger in increasing the size of
include/net/route.h:RT_CACHE_SIZE_MAX in a 2.0.30 kernel???
This apprently controls the maximum size of the IP route cache, and
it's currently set to 256. If I changed it to 2048 (say) would
anything bad happen? :)
Just make sure you make it a power of 2 and you should be OK.
