Hi Pavan,

> 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.

I suppose this patch-set is for 20.02, right?

>       be configured based on Rx/Tx adapter capability.

>     - Each event port is linked to all existing event queues.
>     - Dedicated Rx/Tx adapters for each Ethernet port.
