This patchset adds support for event mode in l3fwd.
The poll mode is still the default mode of operation.

The following new command line parameters are added:
 --mode: Dictates the mode of operation either poll or event. If unset then
         by default poll mode is used.
 --eventq_sync: Dictates event synchronization mode i.e. either atomic or
		ordered.

Based on event device capability the configuration is done as follows:
    - A single event device is enabled.
    - The number of event ports is equal to the number of worker
      cores enabled in the core mask. Additional event ports might
      be configured based on Rx/Tx adapter capability.
    - The number of event queues is equal to the number of ethernet
      ports. If Tx adapter doesn't have internal port capability then
      an additional single link event queue is used to enqueue events
      to Tx adapter.
    - Each event port is linked to all existing event queues.
    - Dedicated Rx/Tx adapters for each Ethernet port.
