[ax25-layer2] clear line in the sand

[nc8q]

<snip>
"One area of concern is that AX.25, or any other implementation, will 
make the layer 1-2 and layer 2-3 boundaries less than distinct. Do we 
draw a clear line in the sand and take great pain to not step over or do 
we do what seems right and deliberately allow these boundaries to remain 
fuzzy?

'Nuff babble for now.

I am with Glenn on establishing a 'clear line' where we can and
put our efforts.  'Gray' areas toward Livel 1 and 3 could be
set and in these areas discussion would be 'almost off topic'.
There should be clear limits set for topics totally in Level 1 & 3.

(1) I would like to see a two column list of what X.25 and AX.25 have
in common and what is different.

(2) Are IP addresses Level 3?
  I thought Level 2 was MAC addressing and no routing information.
  Is digipeating 'routing information' and does it belong in level 3?

(3) Where can I(we) find the X.25 and the AX.25 RFCs or official 
definitions?
