Good catch.  Originally the last 3 commands were only for multicast support, but
I went back and added GET_DST_ATTR as part of the UD QP patch.  I will swap
those around, so that the check-in doesn't change the values.

My intent is to commit the UD QP patch, followed immediately by the multicast
patch, and only update the ABI once.
