Support load distribution in security gateway application using
NIC load distribution feature(Flow Director).
Flow Director is used to redirect the specified inbound ipsec flow
to a specified queue.This is achieved by extending the SA rule syntax
to support specification by adding new action_type of <flow-direction>
to a specified <port_id> <queue_id>.

v2 changes:
added more details in commit message.
added a check to throw an error if the security session type is other than
LOOKASIDE_NONE
