Re: [MEXT] GRE support in DSMIPv6 - AD review

Hesham,

I would strongly suggest moving the whole TLV header text to the
separate GRE document.

In particular, if you assign a number for GRE in this document,
you either need to describe how it works here, or have a normative
reference to the NETLMM spec.

Best regards,
Pasi
