You are correct.  I didn't realize I should embed the data
in the ifr_data area - I thought I needed to pass a pointer.

Now I see why you avoid that.  And since IFNAMSIZ is 16,
there is enough space for the struct mii_ioctl_data.  A bit
dirty, but it obviously works.

Anyway, thanks very much for taking the time to debug my
program, and set me straight.  Naturally, I withdraw the
patch. :-)
