Ok, it makes sense.

Just for curiosity the target setup is the following:

but instead of using internal drivers, we desire to use mainline drivers only.

Thanks!

Regarding this subject, I am thinking of making the following adaption:

a) delete ethernet/synopsys
b) rename ethernet/stmicro/stmmac to ethernet/synopsys

and send you a patch for you to evaluate. Both agree with the approach?
To have a new work base would be important, because I will add to the "new"
structure some missing QoS features like Multichannel support, CBS and later TSN.

IMO, we have to agree on a common strategy making the change for
net-next; I imaged the following steps:

Yes it makes totally sense.

- to port missing feature or fixes from ethernet/synopsys
  inside the stmmac taking care about the documentation too.

@Lars: You are familiar with the synopsys qos driver. Could you please do this
porting. You can also make an analysis of what to port and I can do the porting
for you if you don't have the availability for it.

- remove ethernet/synopsys
- rename ethernet/stmicro/stmmac to ethernet/synopsys

I volunteer to do this task.

  These latest two have some relevant impacts.

  This change should be propagated to all the platforms that are using:
      CONFIG_SYNOPSYS_DWC_ETH_QOS and CONFIG_STMMAC_ETH
  plus device-tree compatibility.

I volunteer to do this task also.

- enhance the stmmac with new features and new glue (part of these
  can be anticipated for sure).

I have to implement 3 new features for now, but I will take some time for it, so
I would suggest to make the previous task and incrementally add features.

what do you think? does it make sense? If yes, we can also
understand how/who starts.

Peppe

Thanks and regards.
