> 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_sched: Dictates event synchronization mode i.e. either ordered,
> 		 atomic or parallel.
>  --event-eth-rxqs: Number of ethernet RX queues per device.
> 
> 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.
> 
> v3 Changes:
> ----------
> - Unify argument parsing.
> - Segregate poll mode and event mode initialization.
> - Simplify event resource creation and accesses.
> - Integrate

> ----------
> - Shorten the structure name `s/event_rsrc/evt_rsrc` `s/l2fwd_rsrc/rsrc`.
> - Use rte_panic instead of rte_exit.
