> A new parameter `hairpin-mode` is introduced to the testpmd command
> line. Bitmask value is used to provide more flexible configuration.
> This parameter should be used when `hairpinq` is specified in the
> command line.
>
> Bit 0 in the LSB indicates the hairpin will use the loop mode. The
> previous port RX queue will be connected to the current port TX
> queue.
> Bit 1 in the LSB indicates the hairpin will use pair port mode. The
> even index port will be paired with the next odd index port. If the
> total number of probed port is odd, then the last one will be paired
> to itself.
> If this byte is zero, then each port will be paired to itself.
> Bit 0 takes a higher priority in the checking.
>
> Bit 4 in the second bytes indicate if the hairpin will use explicit
> TX flow mode.
>
> e.g. in the command line, "--hairpinq=2 --hairpin-mode=0x11"
>
> If not set, default value zero will be used and the behavior will
> try to get align with the previous single port mode. If the ports
> belong to different vendors' NICs, it is suggested to use the `self`
> hairpin mode only.
>
> Since hairpin configures the hardware resources, the port mask of
> packets forwarding engine will not be used here.
