It seems that at EuroBSDCon there was a discussion of Contiki[1] and
the uIPv6 stack[2] that it contains, and I think something like this
could be a great future enhancement for netdump and similar consumers.

Ideally I'd like to see us get to having a clean, simple API for
transmitting and receiving packets and a basic stack that could be
shared by netdump, as well as a network-enabled ddb, gdb backend, and
perhaps console.  Using the uIPv6 stack for this would get us v6 support
(as the name suggests), as well as a supported / maintained stack vs.
what is in netdump now.  It's also BSD-licensed.

This could be a good future project, although I think the current
netdump implementation is worth bringing in soon (taking into account
the good feedback received to date, of course).
