Jobstats seem not related to SR-IOV, you need to describe what's the usage of job stats library.

> +The L2 Forwarding sample application, which can operate in real and

> +performs L2 forwarding for each packet that is received.
> +The destination port is the adjacent port from the enabled portmask, that
> is,
> +if the first four ports are enabled (portmask 0xf),
> +ports 1 and 2 forward into each other, and ports 3 and 4 forward into
> each other.
> +Also, the MAC addresses are affected as follows:
> +
> +* The source MAC address is replaced by the TX port MAC address
> +
> +* The destination MAC address is replaced by 02:00:00:00:00:TX_PORT_ID

> +Running the Application
> +-----------------------

> +The application requires a number of command line options:

> +* q NQ: A number of queues (=ports) per lcore (default is 1)
> +
> +* l: Use locale thousands separator when formatting big numbers.
