net/hns3: support power monitor
Checks
Commit Message
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.

Applied to dpdk-next-net/main, thanks.
