TCP packets getting lost causing same-subnet-tcp-connections to hang

[Vedamurthy Joshi]

Build 2.0 2464 Single node setup

nodeb8 is a single node sanity setup
After provisioning, it was seen that machines on the same subnet as the compute node fail to establish ssh sessions to this compute node.
Machines outside of the subnet are able to ssh fine

Anand would have more details once his debugging is complete

Change the location from where we try to pull the outer headers

The function that pulls outer headers assumes that the packet data
points at layer 2 header. While this is true in case of ubuntu, the
commit that made this assumption did not reposition the call for
Centos, resulting in pull failures.
