Hi again<br>
<br>
I tested Dave's build of cake on wndr3800. (Didn't try specifying
cake2/cake3; I'm guessing tc cake means cake3 on there). "atm"
adjustment worked fine on my adsl. I can't distinguish it from
sqm-scripts with the same configuration.<br>
<br>
SQM seems to win from having "overhead 40", which I can't configure
in cake.<br>

IMO it wouldn't hurt for 'tc atm', 'tc adsl', and everything else to
default to 'overhead 44'. (The highest overhead Seb reported; the
original worst case overhead[1] plus a vlan header for IPTV).<br>
