[pox-dev] Build MAC list

[Amer]

Hello,
I tried it, it works fine.
I tried pox.py forwarding. l2_multi openflow.discovery proto.dhcpd: default 

I received in Debug:
misc.dhcpd [00-00-00-00-00-07 4] no packet
proto.dhcpd [00-00-00-00-00-07 4] no packet

DHCP packet data too short to parse: data len 86

Best regards,
Amer
