From df1bcf90a66a10967a3a43510b42cb3566208011 Mon Sep 17 00:00:00 2001 From: Chengchang Tang Date: Fri, 4 Aug 2023 09:27:08 +0800 Subject: [PATCH] RDMA/hns: Fix port active speed HW supports a variety of different speed, but the current speed is fixed. The real speed should be querried from ethernet.
