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.

SQM seems to win from having "overhead 40", which I can't configure in cake.

	up / kbit/s	down / kbit/s	overhead / bytes	Median RRUL / ms
SQM	16000	950	0	74
Cake	17175	995	0	76

Cake	16000	950	0	74
SQM	17175	995	40	70

DSL sync rate	17619	1020		59

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).
