net: hns3: bugfix for hclge_mdio_write and hclge_mdio_read
When there is a PHY, the driver needs to complete some operations through MDIO during reset reinitialization, so HCLGE_STATE_CMD_DISABLE is more suitable than HCLGE_STATE_RST_HANDLING to prevent the MDIO operation from being sent during the hardware reset. Fixes: b50ae26c57cb ("net: hns3: never send command queue message to IMP when reset) Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
