In the NF_IP_POST_ROUTING hook function, how can I
tell that packet originated locally vs was forwarded ?
I need to hook NF_IP_POST_ROUTING not NF_IP_FORWARD.
I'd expect that 'net_device *in' argument to be not NULL for
forwarded packets.
But what I see is NULL for both forwarded and locally sent packets
(in NF_IP_POST_ROUTING hook).
Which field of skb can tell me that packet originated locally ?
