This patch support querying information of Tx queues.
The command is like:
--> /ethdev/tx_queue,0,0
{
"/ethdev/tx_queue": {
"host_threshold": 0,
"prefetch_threshold": 0,
"writeback_threshold": 0,
"rs_threshold": 32,
"free_threshold": 928,
"deferred_start": "off",
"offloads": [
"MBUF_FAST_FREE"
],
"queue_state": 1,
"nb_desc": 1024,
"burst_flags": 0,
"burst_mode": "Vector Neon"
}
}
