- Changes to support cross connect without scripts
  - agent alive/dead detected based on addition of pkt0 vif and removal of
    pkt0 interface from the system (OS)
  - on agent's death, all vhost interface and their corresponding physical
    interfaces are put on cross connect mode where the traffic will still
    pass through vrouter
  - from the time of reset till vhost gets added back again, traffic moves
    directly from physical interface to vhost
  - once vhost interface is added, traffic flows normally through vrouter

- Vlan tagged packets are handled different between 2.6 (Centos) kernel
and later kernels. To make handling uniform in all platforms, push the
vlan header in the packet for the later kernels

- Ensure that inner header checksums are correct on the wire when the outer
header is UDP (MPLSoUDP or VXLAN).

- Outer UDP header source port is now a hash of inner header 5-tuple.

- interface notifier argument changed in 3.11 kernel. Add #ifdefs
to accommodate that change

Make vrouter coexist with Linux bridge (and not coexist with OVS).

BUG:1336717
Do trap + forward the packet when the packet arrives from an ECMP source
that was different from the destination of the forward flow

[ forward port into mainline ]

BUG 1340528

- For ICMP error packets, the flow key has to be the same as that of the
original payload. This is because, in a floating IP case, default security
group rules allow only outgoing packets originated by the VM and incoming
packets to VM that belong to the same security group. Packets originated
from the destination floating ip network does not belong to the same security
group and hence will be dropped if we use the outer IP header for forming the
flow key.

Another issue is with the NAT-ing. The ip header source ip and destination ip
+ transport header ports in the icmp error payload have to be NAT-ed back.
