This issue cannot be reproduced if only SFP module is connected and fiber cable is disconnected before configuring flow control even though link is down in this case too. This patch improves it by getting configuration values from dpni_get_link_cfg API instead of dpni_get_link_state API, which provides us static configuration data.
