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 ?
