Maybe i can help.
Mostly problems with auto-negotiation it seems. Earlier 2.4 kernels just would never go 100bt/FD. Later (broken) versions would claim to be 100bt/FD, but they still showed lots of collisions and frame errors.
I'll try the ZYNX on the latest kernel in the next few days and let you know what I find...

The API has been there since 2.1.x, and yet few drivers support it? I can see why Ingo decided to fix the problem generically. I think it would be great if his code printed a log message upon trigger that basically said: "You should get yourself a NAPI enabled driver that does flow-control if possible." That may give the appropriate visibility to the issue and let the driver writers improve their drivers accordingly...
