Yes, you are right.
Remember, Jamal ACKed the patch, and you redrew your NAK.

This is not a ATM/ADSL only patch.  This patch simply adds more 
flexibility to the rate tables.  Afterwards we can start the discussion 
about how to use this new flexibility in tc/iproute2.

BTW. The reason you could not measure any improvements on your SHDSL line 
is that it uses HDLC and not ATM as data link layer.

See your,
