Here is a patch against 2.4.8 that implements support for diverting network frames
to an arbitrary kernel module. It is similar to the user-level packet diverter
except that it handles both incoming and outgoing packets, and the module can
discard the packet if it wants to. There is also a callback when a packet is freed.
This allows a modular way of doing low-level packet frobbing without going out to
userland.

As noted in the code, it currently only supports 1 'diverter module', but it would
be pretty easy to support more...

Comments? Anyone find this sort of thing useful besides us?
