Subject: [RFC PATCH net-next 00/14] Offload tc-flower using VCAP chains

This is the result of this discussion:
https://lkml.org/lkml/2020/6/2/203

RFC because there are still some TODO items:
- I haven't added VCAP fields to Ocelot and to Seville, mostly because I
  don't understand how to derive the ENTRY_WIDTH setting. Would
  appreciate some help there. I've only tested this on Felix.
- The selftests script is rather bare bones, not sure what to add to it
  to make it more comprehensive. Understanding that this is the go-to
  reference for any user, it would need to be pretty clear how the thing
  can be used.

Comments appreciated.
