Too many duplicated code, prefer to reduce them as following:

for port in ports:
        netdev = self.dut.ports_info[port]['port']
        driver_now = netdev.get_nic_driver()
        if driver == "":
            driver = netdev.default_driver
        if driver != driver_now:
                    netdev.bind_driver(driver=driver)
