Hi All

Forwarding packets (routing) in kernel 2.0.34 uses memcpy to copy
contents of a buffer from certain socket buffer that was received to
another socket buffer that is allocated to the destination interface ;
this method uses lots of CPU time which makes routing performance very

is this problem solved in higher version of kernels ? or any one have a
simple solution for this issue ?

thank you
