Hi all,

This small rev to rfc6824bis applies the two changes proposed by Fabien which had support on the list:

- The flag on MP_CAPABLE to say “do not connect back to this address” (proposal 1/5)
- The echo flag to make ADD_ADDR reliable (proposal 2/5)

The “do not use this address unless nothing else is available (proposal 3/5) did not appear to have much support on the list so has been left out for now.

Proposals 4 and 5 are MIA so have not been added at this stage ;-)

Cheers,
Alan
