X-Surf (was: Re: Ethernet support)

[Geert U. <ge...@li...>]

I think the patch below converts the Ariadne II driver into a driver for the
X-Surf. If it works, I'll be happy to integrate it with the Ariadne II driver
into one ne2k-zorro driver.

Notes:
  - I assume the RTL8019AS on the X-Surf is not in PnP mode. Else we first
    have to do ISA PnP isolation and assignment.
  - At first I thought I could easily convert the Ariadne II driver in a Hydra
    driver as well, but this didn't turn out to be the case. The Hydra doesn't
    seem to have the 8390 reset register and the 8390 data port register
    (there's only 0x1f space for registers, at even offsets). I guess that's
    why the old Hydra driver accesses the on-board RAM directly instead of
    through the 8390 data port. But I'm sure a driver can be written that uses
    the generic 8390 driver core, it's just a bit more work.
  - From reading the specs, the X-Surf also seems to have 2 IDE interfaces. It
    doesn't seem to be that difficult to support, so if someone is interested
    in a driver, please speak up.
  - Anyone who knows what else is on the X-Surf that's worth to support?

Disclaimer: I don't own any NE2000 compatible Amiga Ethernet cards. But I do
wish you good luck! :-)
