Subject: RE: [PATCH 0/4] Add a driver for the ASIX AX88172A

Dear All,

>From ASIX support viewpoint, it might be hard to support all AX88172A target applications on Linux kernel native ax88172a.c driver because some of AX88172A applications are embedded on customers' special target applications such as the AX88172A (PHY mode or Dual-PHY mode) + external MAC controller on-board design applications. For these kinds of AX88172A applications, the AX88172A Linux driver was qualified in our customers' site directly. It means ASIX doesn't have those customers' AX88172A devices in our site for testing. 

But for some AX88172A target applications such as AX88172A + external Fiber PHY and AX88172A + external National DP83640 PHY (Christian is testing under), etc. USB dongle applications, it is possible to support them on Linux kernel native ax88172a.c driver but *** the readme of this driver source might need to indicate clearly what kinds of AX88172A devices had been verified on this ax88172a.c native driver source ***. It will avoid users were confusing why their AX88172A devices couldn't work fine on Linux kernel native driver in future. 

Please let us know if you need more information. Thanks a lot.

I'll second that.  Ideally, somebody should pick up the pieces
from my aborted efforts last fall, and just get the real ASIX driver
itself tidied and into the kernel.  Then *everything* would work.

But I doubt that would be feasible at this point.

Cheers
