[6lo] mic comment about layers

[Alexandru Petrescu <[e-mail]>]

Hello,

I wanted to make a comment at the mic about layering, during the IANA 
registry discussion.

As I hear the discussion about liaison with ITU, it looks to me as a 
ping-pong of statements.

Who is responsible to allocate these codepoints - IANA or ITU?

Even if IANA makes a registry for it, are we sure that ITU will not 
allocate in the future other codepoints beyond what IANA allocates?  
And, should we care?

My oppinion on this is that IANA should not allocate numbers to whatever 
runs below IPv6 headers.

Let the underlying layers (below IP) offer IEEE-like interfaces, with 
EtherTypes.  That's what works.
