Re: [ieee-ietf-coord] RFC8691 and 802.11bd

[Alexandre Petrescu <[e-mail]>]

Peter,

Thanks for the clarification.  Sorry missing a first reply back in July,
despite careful attention.

It makes sense at MAC layer to stay independent of the upper layers,
including IP.

Some interactions might be helpful, though.  RFC8691 conditions the use
of .11 QoS headers for using IPv6, and as such one would like to make
sure .11bd is able to do these .11 QoS headers.  Otherwise IPv6 wont
work on .11bd, unhappily.

.11 documents often mention 'MIB' and sometimes might mention 'IP' or
'192.'.  That is a sign that .11 might depend on SNMP and further on IP,
even though not very explicitly.  If so (if .11bd D2 mentions 'MIB' or
'SNMP' or '192.') then one would like to make sure the current version
of IP is supported, explicitely.

Can I check that?

Alex
