Ying Xie dc2fb747a5 [ebtables] install ebtables in base image and install filter rules
- Add ebtables package, and install some filter rules:
  1. ebtables -A FORWARD -d BGA -j DROP
  2. ebtables -A FORWARD -p ARP -j DROP

Basically, we let the ARP packets in the VLAN being forwarded by the ASIC,
kernel gets a copy of these ARP packets and the forwarding from Kenerl gets
dropped. So there is always only one copy of ARP/response in the VLAN.
