RFMIBv2 ID-nits: references

Check ID nits and other comments made by mib doctors in other drafts.
   http://www.ietf.org/ID-nits.html

There are normative references that are not even mentioned once and not used as IMPORTs in the document:
   [1] Woundy, R., "Baseline Privacy Interface Management
       Information Base for DOCSIS Compliant Cable Modems
       and Cable Modem Termination Systems", RFC3083, March 2001.
   [9] "Adapted MIB-definitions and a clarification for MPEG-related 
       issues for EuroDOCSIS cable modem systems v1.01", tComLabs, 
       May 2000., available at http://www.tcomlabs.com. 
Suggestions:
  - call this reference in the text or just remove it;
  - I cannot find the named reference under http://www.tcomlabs.com ; if you keep it, then we need a better link, especially if it remains normative.


Also, should [6] be made informative instead of normative?
(a) it's a book 
(b) the DOCSIS specs are referenced normatively and that's where a normative reference on QPSK should be.

PS: also, CableLabs is working on a stable HTTP URL for our specifications so the http://www.cablemodem.com URL will most likely have to be updated. More on the actual URL soon.
