Subject: [PATCH net 1/4] net: hns3: fix output information incomplete for dumping tx queue info with debugfs
Date: Fri, 12 May 2023 18:00:11 +0800 [thread overview]
Message-ID: <20230512100014.2522-2-lanhao@huawei.com> (raw)
In-Reply-To: <20230512100014.2522-1-lanhao@huawei.com>
From: Jie Wang <wangjie125@huawei•com>
In function hns3_dump_tx_queue_info, The print buffer is not enough when
the tx BD number is configured to 32760. As a result several BD
information wouldn't be displayed.
So fix it by increasing the tx queue print buffer length.
Fixes: 630a6738da82 ("net: hns3: adjust string spaces of some parameters of tx bd info in debugfs")
