				stallamr_netapp.comUnsubmitted Not Done Inline Actions This change appears to suppress "unqualified module" message if the link for any reason go down. For instance - admin down vs really an unqualified/unsupported module. If let say, I inserted a SAS cable or FC cable against the port, naturally the link is down but we will loose the ability to advertise "unqualified module" as well. stallamr_netapp.com: This change appears to suppress "unqualified module" message if the link for any reason go down.
				krzysztof.galazka_intel.comAuthorUnsubmitted Done Inline Actions The IFF_UP flag is controlled by ifconfig and it does not depend on the state of a link reported by FW. When interface is brought up by an user and FW reports link down due to unqualified module the message is going to be reported. krzysztof.galazka_intel.com: The IFF_UP flag is controlled by ifconfig and it does not depend on the state of a link…
