Virtex-4 TEMAC device driver available?

[Yoshio Kashiwagi]

Hello Steve San,

Although I was performing porting for the reference design of
xapp902 shown in the following URL, I have noticed that the
temac circuit of this xapp902 cannot perform control of PHY.
The temac circuit of this xapp902 does not have control of PHY.

As a result of consulting with our client, our client newly
creates their original temac based on xapp807 design of the
following URL. It is because the function is insufficient
using Linux in this xapp897 design.

Since I created the temac driver of their design, the release
of the driver to ML became impossible to me.

Best Regaeds,
