Vyos patches

• linux-image.git.patch
  • MACVLAN_MODE_VRRP only moves vrrp multicast packets back to the lower interface. All other packets are left on the upper device. The vyos keepalived does all the vrrp communication over multicast on the lower device, but we need the ARP packets to show up on the upper device.
• vyatta-cfg-qos.git.patch
  • add small packet matching
• vyatta-ravpn.git.patch
  • idle timeout and ESP lifetime options from <http://www.proppedup.org/2011/09/28/vyatta-6-3-remote-access-patch/>
