Wolfgang, I just sent out v4. Any chance to give this patch a try? It
would be best to use a recent kernel version but I could also adapt the
patch to your kernel version, 2.6.39, I think!?

As you are using a CC770 chip, I'm especially interested in the relevant
kernel log (dmesg) and "ip -d -s link show".

Thanks,

Wolfgang.
