I’m good with a separate proposal to address the GMAC issues

Hey Bob,
I’ve attached a version of your document with some comments added.
Let me know what you think,
Thanks,

Thanks Dave.RE 'Zero is always acceptable' is just missing a period. It relates to the value of ulIvFixedBits in the previous sentence.
GMAC comments. I did not change this section, so I would prefer to handle any issues there separatelyfrom the AES GCM part of the spec. I think you did identify at least issues with the existing spec, as well as possible enhancements to GMAC itself. I certainly
would entertain a proposal to independently update the GMAC portion of the spec.;).

Submitter's message
This is an update to the AEAD to handle the comments from the previous call, namely a desire to have a way to handle externally generated IV's.
I implemented this generally by creating a Generator Function parameter and defining 4 generator operations. In the future more could be added (like tls 1.3 if it differs from any of the existing generators).
I only require the generic generator to be implemented. I also allow that the application can provide the fixed portion of the IV/nonce as well as a new parameter to specify how long the fixed portion is in bits.
