4e0c9bfd02 fixed logic errors in handling of nexthop and destination addresses
when receiving a frame and determining if it is broadcast etc.
(one major use case that has been fixed is broadcast nexthop, and
unicast destination, e.g., for link-local broadcast).

e636dcd0fc Fixed handling of broadcast frames so that not-forwarding a broadcast
frame does not equate to not examining its contents ourselves.

2802a5c042 Fixed bug in dequeuing broadcast frames after they have been
sent via interfaces.
Also some debugging output added.

752a29c112 Fixed handling of duplicate broadcasts (they get dropped sooner).
There does seem to be something odd about the broadcast processing
still, as the BPIs change after resolving addresses.
Maybe when we send a broadcast out via multiple interfaces it
gets marked duplicate after sending to the first interface?

aa543e1766 Various fixes and work towards MDP ping working.
MDP clients can now request the set of local addresses.
Framework is improved to avoid info leaks by sending more bytes
in an MDP frame than are necessary, but without having to bzero
almost 2KB each time.

70497df7b5 More work on MDP. Removed some debug fluff.
Added framework for MDP ping, and some work towards MDP port binding
and sending packets with option to wait for reply.  MDP server
doesn't yet support port binding, and client doesn't yet support
reading replies.

2a3721506b More debugging output fixes and bug fixes for overlay operation.
Added proper check to suppress frames claiming to come from
ourselves ( necessary for squelching multi-hop broadcasts, although
we need an extra step there of having transaction ids on broadcast
frames so that we can flood smartly).
