Hi Florian

Looks O.K. to me. I can test it out later.

Is there a bigger picture here? Do you plan to remove the second
net_device parameter everywhere?

Its tempting, seems only af_packet uses it.  I'll see if there is
another (simpler) way of getting the orig ifindex into af_packet.

FWIW, I still have some changes queued locally that make use of orig_dev
to support the switch tag HW insertion/extraction, but I think "dev"
here is equally suitable since it still points to the DSA master network
device.

I'll apply this for now.

Andrew says it looks OK, and if Florian F. needs it for his tag changes
we can revert.
