------- Comment #12 from guy@xxxxxxxxxxxx  2007-04-11 19:39 GMT -------
I don't see any 802.1AB-2007 on the shop.ieee.org Web site.  The page at

    http://www.ieee802.org/1/pages/802.1AB-rev.html

mentions some 2007 802.1AB drafts.  Is the engineer in question referring to
one of the drafts?

All 802.1AB-2005 says is that it's "an integer value as defined by the
ifMauAutoNegCapAdvertisedBits object in IETF RFC 3636."  RFC 3636 declares
ifMauAutoNegCapAdvertisedBits as "OBJECT-TYPE SYNTAX BITS", and RFC 1906 says
that's done as an OCTET STRING.

Perhaps the intent is to clarify this in 802.1AB-2007, which would, I think, be
a Good Thing, especially given that the evidence appears to be that hardware
exists that interprets the standard in both ways (0 means bottommost bit and 0
means topmost bit).
