6759a26720 Cleaned out some debugging output after tracking down and fixing 
memory corruption bug.  Next challenge is to find out why broadcast
MDP packets are not getting dispatched properly (is trying to treat
broadcast address as unicast address it seems).
 2012-03-23 07:06:57 +10:30
gardners
c7dd475d50 Further work on MDP, including dispatching low-priority data when 
it can fit in frames.  A nasty bug in queue code needs fixing.
Also, we only send tick frames at present, and need to add code
for dispatching packets at other times (bandwidth allowance permitting).
So the whole bandwidth management code needs to get finished.

gardners
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).

2a2f8d752f reception and processing of advertised routes now works :)
