This was enough to leave my upgraded 1.2.6 -> 1.3 RC1 machine without an internet connection, that section/ifb redirect was working prior

Event Timeline

@trystan attach please configuration with sets, how to reproduce it.
For example

set param xxx option xxx..
set param2 xxx .option xxx..

And after commit... tc error..

It will be faster, to reproduce it.

The same config now commits however the fq-codel shaper that was functional in 1.2.7 that's applied to it does not activate in 1.3.0-rc4

The config is taken right from the ifb0 fq-codel example on the wiki
