Subject: [PATCH net 3/3] net: hns3: fix setting incorrect phy link ksettings for firmware in resetting process

From: Guangbin Huang <huangguangbin2@...wei.com>

Currently, if driver is in phy-imp(phy controlled by imp firmware) mode, as
driver did not update phy link ksettings after initialization process or
not update advertising when getting phy link ksettings from firmware, it
may set incorrect phy link ksettings for firmware in resetting process.

So fix it.
Fixes: f5f2b3e4dcc0 ("net: hns3: add support for imp-controlled PHYs")
Fixes: c5ef83cbb1e9 ("net: hns3: fix for phy_addr error in hclge_mac_mdio_config")
Fixes: 2312e050f42b ("net: hns3: Fix for deadlock problem occurring when unregistering ae_algo")
