first compiling goes well.
1) Working demo of capture packets on 'eth1', like:
....
Ethernet: MAC[00:23:4E:DA:90:65]->[14:D6:4D:CA:65:34] type[0800]
IP: Version: 4 HeaderLen: 5[20] TotalLen 52 IP
[173.194.34.132]->[192.168.0.103] 6[TCP] PORT [443]->[60002]
....
2) Still need to verify if it works for 'monitor mode'.
