After reading more carefully the RFC I noticed that for now it
only supports CBS. CBS is already supported by stmmac since:
"net: stmmac: configuration of CBS in case of a TX AVB queue"
[1]. My main objective now is to add support for EST and FP
features in stmmac.

As I am a recent contributor to net subsytem I am afraid my
expertise won't be of much value for now as far as the RFC goes.

About my patches, what I think would be better now would be to
drop the configuration by DT and integrate the remaining
configuration, letting the EST parameters be populated by SoC
specific wrappers. I will then integrate this with the RFC
patches once they get in and I also intend to contribute with the
discussion once a new version is sent.

I need also to say that this was fully tested and its working as
expected so, there is no real setback in integrating this now and
it will save us time in the future because then we will only need
to implement the callbacks.

Best regards,
Jose Miguel Abreu
