The purpose of this patch is to add more comprehensive support for flow offloading in the mscc_ocelot library and switch drivers.
The design (with chains) is the result of this discussion: https://lkml.org/lkml/2020/6/2/203 Still posting as RFC because there might still be some bugs and missing checks, and I would not like this to get merged before hearing some feedback. I have tested it on Seville VSC9953 and Felix VSC9959, but it should also work on Ocelot-1 VSC7514.
