[PATCH net-next v2 4/9] net: microchip: sparx5: Adding initial tc flower support for VCAP API

[Casper Andersson]

Hi Steen,

It's a pretty big patch series, but overall I think it looks very good.
I've got some minor comments. I also tested it on the Microchip PCB135
switch and it works as described.

Could this also be shared in the VCAP API? It currently doesn't use
anything Sparx5 specific. Though, net_device is unused so I'm guessing
you might have plans for this in the future. And it might fit better
here according to your design goals.
