[realtek] Flash programming fix for rtl8139-diag

[Mikkel Lauritsen]

Hi all,

After having poked around a bit I've managed to make my
generic 8139C based NIC actually program an AT29C256-120
flash prom.

The patch below contains the not very documented changes
that I've made. Is this the right way to go about reporting
fixes like this? I haven't been able to test it with other
versions of the 8139, but at least it works for me.

Regards,
  Mikkel Lauritsen
