- From the af_packet point of view, is was "the real original device
- that received the packet".

As bonding don't use orig_dev anymore, the remaining meaning should
logically be "the real original device that received the packet". But
as __netif_receive_skb() is recursively called in many cases, setting
orig_dev to something new every time, this meaning is probably mostly
inconsistent. As such, it sounds appropriate to remove orig_dev and
use skb_iif instead.

I don't think we can, otherwise people who set po->origdev will no
longer get what they expect.

For the simpler cases of bonding and VLANs, it does currently behaved
as expected.

That's why I left it alone.
