Subject: [PATCH v9 7/8] app/procinfo: support descriptor dump
Date: Sat, 8 Oct 2022 18:53:52 +0800	[thread overview]
Message-ID: <20221008105353.18195-8-liudongdong3@huawei.com> (raw)
In-Reply-To: <20221008105353.18195-1-liudongdong3@huawei.com>

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.
