I disagree with the interpretation of M=0.

M has no impact on stateless autoconf.  The existence
of prefixes in the RA marked as "autoconf from this
prefix" controls stateless autoconf.  If M=0 and no
prefixes are advertised as autoconf-able, the host
has no assertion that DHCP is available and no prefixes
to autoconf addresses from.

If M=1 and autoconf prefixes are available, the host
does both DHCP and stateless autoconf.

My thinking is:

M=0, O=0 stateless autoconf of addresses
M=0, O=1 stateless autoconf of addresses + information-request
M=1, O=0 stateful autoconf of addresses

It seems from these discussions that a more precise representation might be:

 M=0, O=0 stateless autoconf of addresses
 M=0, O=1 stateless autoconf of addresses + information-request
 M=1, O=X stateful autoconf of addresses + information-request

where, X  = "Don't-Care". Does this match up with the emerging
consensus? Is there really nothing better to be done with the
"O" bit when the "M" bit is set?
