Hi Arnd,

Actually after rereading this, I realised that I completely forgot your former
comment about having a NULL parameter for network devices (as there is no
requestor behind).

I will cook it up for v3 ... that will be a minor change in this patch (hence
I'll keep any Ack), but for patches 0006 and 0007, things will change, and
another patch for Vinod will appear.

Cheers.
