You are enqueing packets in the localout hook.

#define NF_IP_LOCAL_OUT         3

yes, in localout hook the packets are in network layer, so they don't 
still know anything about the link layer information, that is, mac 
address and folks.

Hi all, i'm new to netfilter and just started trying some simple things.
I've made a program (simple program) to take a packet and print its metadata.
The output is this:

ID of queued packet: 3413885640
Netfilter mark value: 0
Packet arrival time (seconds): 0
Packet arrival time (+useconds): 0
Netfilter hook we rode in on: 3
Name of incoming interface: 
Name of outcoming interface: eth0
Hardware protocol: 0
Hardware type: 0
Hardware address length: (null)
Hardware address: 
Length of packet data: 0


Is this result valid? most values are 0
