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

[George Tsirtsis <[e-mail]>]

I think what Pasi suggests makes sense and will make things easier for
whoever defines GRE support.

Not assigning a number for the TLV essentially means that the TLV
header for GRE is undefined and thus nothing needs to be said about
it. The whole thing can then be defined in a different spec as needed.
