Subject: [PATCH v2 10/13] ethdev: support telemetry query DCB info
Date: Wed, 7 Jun 2023 15:42:05 +0800 [thread overview]
Message-ID: <20230607074209.4798-11-haijie1@huawei.com> (raw)
In-Reply-To: <20230607074209.4798-1-haijie1@huawei.com>
This patch supports querying DCB info.
The command is like:
--> /ethdev/dcb,0
{
"/ethdev/dcb": {
"tc_num": 1,
"tc0": {
"priority": 0,
"bw_percent": "100%",
"rxq_base": 0,
"txq_base": 0,
"nb_rxq": 4,
"nb_txq": 4
}
}
}
