[Cake] bringing up a new router/connection

Thu Feb 4 00:14:38 EST 2021

I replaced the c2600 with the Turris Omni (one of the kickstarter ones) and 
setup cake on it. This is running the Turris version 5 OS, which is supposed to 
closely track upstream openwrt (let me know what I can do to check versions as 
needed)

download wise I get good performance at 300000 download, but upload is still 
having problems, mostly just getting 10-15Mb even with the rate set to 0 to 
bypass cake entirely

eth2 is the DSL, lan4 is the cablemodem (lan4 is a switch port, probably 
accessed via eth1)
