Tc replace command doesn't change diffserv classify with cake. #156

When I want to change diffserv4 to 3, tc replace command doesn't change it.

Before tc qdisc replace dev "$dev" handle 1: root cake diffserv4 dual-srchost nat bandwidth "$upload" bridged-ptm mpu 64 ack-filter nowash

After tc qdisc replace dev "$dev" handle 1: root cake diffserv3 dual-srchost nat bandwidth "$upload" bridged-ptm mpu 64 ack-filter nowash

Works for me:

$ sudo tc qdisc replace dev testns handle 1: root cake diffserv4 dual-srchost nat bandwidth 100kbit bridged-ptm mpu 64 ack-filter nowash $ tc qdisc show dev testns qdisc cake 1: root refcnt 9 bandwidth 100Kbit diffserv4 dual-srchost nat nowash ack-filter split-gso rtt 100ms ptm overhead 22 mpu 64 $ sudo tc qdisc replace dev testns handle 1: root cake diffserv3 dual-srchost nat bandwidth 100kbit bridged-ptm mpu 64 ack-filter nowash $ tc qdisc show dev testns qdisc cake 1: root refcnt 9 bandwidth 100Kbit diffserv3 dual-srchost nat nowash ack-filter split-gso rtt 100ms ptm overhead 22 mpu 64

What version of cake and tc are you using where it doesn't work?

Excuse me. Raspberry pi OS uses maybe old cake like Debian stable.
