[PATCH v3 2/3] app/testpmd: Add support for pool sort capability

[Hanumanth Pothula <hpothula@marvell.com>]

This patch adds support for the pool sort capability.
Some of the HW has support for choosing memory pools based on the
packet's size. The pool sort capability allows PMD to choose a
memory pool based on the packet's length.

Populate Rx Sort/Split attributes based on the Rx offload value.
Also, print pool name on which packet is received.
