To revert to standard QCS CLI or QCC GUI control over the Marvell DCB feature
set, uninstall the Microsoft QoS feature or disable quality of service in the QCS
CLI, QCC GUI, or Device Manager NDIS advance properties page.
Marvell recommends that you do not install the DCB feature if SR-IOV will
be used. If you install the DCB feature, be aware that selecting Enable
single-root I/O virtualization (SR-IOV) in Virtual Switch Manager forces
the underlying adapter into a DCB state in which OS DCB configuration to
be ignored, and DCB configuration from QCS CLI or QCC GUI becomes in
effect. However, the user-configured Networking Priority value (nonzero)
does not take effect, even though it appears that it is from QCS CLI or QCC
GUI.
