Subject: RE: [PATCH 1/1] net: add dm9620 net usb driver

Dear Peter,

  This is Joseph CHANG, I am glade to contact and work with you.
  I am busy in some affairs else these days, and will like to be back soon.

  For the begin, We copy the source code 'dm9601.c' which was by you,
   In order to work for our new chips (DM9620, DM9621, DM9621A... series),
   We did modify to get 'dm9620.c' base on 'dm0601.c',
   Since you are the author and also the owner, so keep MODULE_AUTHOR() as you.

  To generate DM9620.c is a way to distinguish the different generation chips:
(as below)

   DM9601: old revision:     USB1.1, Ethernet 10/100,     Phase out
   DM9620: current revision:  USB2.0, Ethernet 10/100,     Mass production state
   DM9633: next revision:    USB3.0, Ethernet 10/100/1000, Will to release on

  So want to make it from the configuration by "make menuconfig".

  Can you help give further advices, we hope you can go ahead be the owner
(author) of the 
  'dm9620.c', And then we make patch to it. Would you agree this idea? If so we
will be happy
  because we did not ever create such a code.

  * Think about DM9633 driver to be, It will be is total different compare to
DM9601 & 
    DM9620. And will get the same issue.
ThankYou and Best Regards,

But dm9601.c already supports the dm9620 based devices. Why another
driver for the same hardware?

Please CC me on dm9601 related patches.
