hi,

it seems that openflow implementations disagree about OFPMBT_ and
encoding of ofp_meter_features.band_types.  (see below)
can anyone clarify which is spec-wise correct?  i peeked the spec
but it was unclear to me.  i'm afraid that other feature bitmaps
have similar problems.

linc:
    OFPMBT_DROP = 0   # this seems like a bug
    band_types = (1 << OFPMBT_DROP) = 1  # would be 2 with the above bug fixed

ovs:
    OFPMBT_DROP = 1
    band_types = (1 << (OFPMBT_DROP - 1)) = 1
    # ofputil_meter_band_types_to_name has a comment saying "assume"...

trema-edge:
    OFPMBT_DROP = 1
    band_types = (1 << OFPMBT_DROP) = 2
