Hi again

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.

overhead / bytes

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).
