several issues about MLDv2

[guyong]

I'm testing MLDv2, but there seem to be some issues, could anyone confirm them?

1. RFC3810 clause 6.1 mentions there is a Source Retransmission Counter associated to each source, so that the merged report could contain the content that is interrupted by a new state change report.
   
   BUT, I didn't see this is implemented!
   
2. Regarding the 'Older Version Querier Present timer', the code is like this:
   

   old_version_timer = (mli->mli_rv * mli->mli_qi) + mli->mli_qri;
   while mli->mli_qri = maxdelay, and maxdelay = ntohs(mld->mld_maxdelay).

   
   BUT, mld_maxdelay is in units of milliseconds (clause 5.1.3), I think it should be divided 1000 before it adds to old_version_timer.
   
3. According to RFC, a node MUST accept and process any Query whose IP Destination Address field contains *any* of the address (unicast or multicast) assigned to the interface on which the Query arrives.
   
   BUT, I see the code only accept General Query addressed to FF02::1.

P.S. I was talking about the the MLDv2 implementation in the FreeBSD kernel in post above.

You're probably better off asking this question at the freebsd-net mailing list, because that's where the developers are.
