This patch support Rx/Tx descriptor dump
The command is like:
dpdk-proc-info -a xxxx:xx:xx.x --file-prefix=xxx --
--show-rx-descriptor queue_id:offset:num
dpdk-proc-info -a xxxx:xx:xx.x --file-prefix=xxx --
--show-tx-descriptor queue_id:offset:num
queue_id: A queue identifier on this port.
offset: The offset of the descriptor starting from tail.
num: The number of the descriptors to dump.
