I want to trace packet movement, syscalls, and other functions called, using

source code for etherstub and VNIC.
Unfortunately that's not possible at present because there's no universal
packet identifier that is preserved for the lifetime of a packet as it moves
through the kernel.
Things like the pointer to the structure that hold that packet can only be
used in a limited fashion because the packet can be rebuilt into a
completely
new data structure and that passed on. But even if you do that, how do
you trace it?
The problem is widely accepted but there's no solution yet.
