We have an abstraction for programming switch devices called DSA.

Even if DSA doesn't fullfill your needs, doing adjustments using sysfs
files in userland is going to be the worst user experience possible.

Every driver will export different things to tweak, each device will
have different semantics and limitations for these settings, etc.

Better is to come up with a real, types, interface for programming
such devices and providing an implementation of that.

I'm not applying this, sorry.
