From 4ae97cae07e15d41e5c0ebabba64c6eefdeb0bbe Mon Sep 17 00:00:00 2001 From: Yu Xiao Date: Tue, 2 Aug 2022 10:33:55 +0100 Subject: [PATCH] nfp: ethtool: fix the display error of `ethtool -m DEVNAME` The port flag isn't set to `NFP_PORT_CHANGED` when using `ethtool -m DEVNAME` before, so the port state (e.g. interface) cannot be updated. Therefore, it caused that `ethtool -m DEVNAME` sometimes cannot read the correct information. E.g. `ethtool -m DEVNAME` cannot work when load driver before plug in optical module, as the port interface is still NONE without port update. Now update the port state before sending info to NIC to ensure that port interface is correct (latest state).
