In bnxt_update_phy_setting(), ethtool_get_link_ksettings() and bnxt_disable_an_for_lpbk(), we inconsistently use netif_carrier_ok() to determine link. Instead, we should use bp->link_info.link_up which has the true link state. The netif_carrier state may be off during self-test and while the device is being reset and may not always reflect the true link state. By always using bp->link_info.link_up, the code is now more consistent and more correct. Some unnecessary link toggles are now prevented with this patch.
