Asix Ax88790 Driver For Socket Rugged Cf 10/100 Ethernet, Is this available for the Angstrom on Zaurus? Options

[Jon_J]

I have this CF ethernet card, which uses Asix AX88790 driver
Has anyone used this card in 2.6 kernels?
I read somewhere that the AX88790 driver is only available for 2.6 kernels.

Socket Rugged CF 10/100™ card
Model number: EA2917 - 722, Rugged CF 10/100 Ethernet
Additional info - this card uses this chip:
The Rugged CF 10/100 card utilizes the Asix AX88790 L 10/100BASE 3-in-1 PCMCIA Fast Ethernet Controller.

I'm not giving up easily on this card since it is brand new, and I cannot return it.
Here is a post about someone getting this working for 2.6 kernel
http://www.mail-archive.com/linux-pcmcia@l...g/msg00051.html

Socket indicates that this chip has a Phy bug and they provide a workaround.

It looks like this is what you need:

[Jon_J]

Thank you for looking into this for me.
It looks like there isn't any for Zaurus. The listings are either simpad, or h220, or hx4700.
And I think I need AX88790, not AX88190. (I'm not sure of this though.)

One more thing to add to my build list...

[Jon_J]

I think I can use the AX88190 driver, if it is available.
It does mention that this is a patch against 2.6.15
Does that mean it will not work with 2.6.24 kernel?
The phy bug work around is shown here, and seems to use the AX88190 driver

    I'm guessing that  the problem is only in a recent revision (the L
    revision?) of the chip since I don't see such a workaround in the
    standard axnet_cs.c driver.

    Has anyone done this workaround? Any other comments or suggestions?
    Otherwise, I'll try to implement these changes and submit a patch.

Here's a patch (against 2.6.15) that works with the Socket Rugged CF
10/100 Card. Comments welcome.

mdelay is going to busy-wait for 2.5 seconds; can you not msleep()
instead?  I don't think you're holding any locks at this point, nor do I
think you're in interrupt context, so sleeping should be OK.

Yes, you are correct, and that works fine. Thanks.

I'd guess that the patch either applies fine or is added in upstream.
