Subject: [PATCH] net/hns3: support power monitor
Date: Mon, 5 Feb 2024 16:35:21 +0800 [thread overview]
Message-ID: <20240205083521.3782951-1-haijie1@huawei.com> (raw)
From: Chengwen Feng <fengchengwen@huawei.com>
This commit supports power monitor on the Rx queue descriptor of the
next poll.
Note: Although rte_power_monitor() on the ARM platform does not support
callback, this commit still implements the callback so that it does not
need to be adjusted after the ARM platform supports callback.
