To revert to standard QCS control over the QLogic DCB feature set, uninstall the
Microsoft QoS feature or disable quality of service in the QCS or Device Manager
NDIS advance properties page.
NOTE
QLogic 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 becomes in effect. However,
the user-configured Networking Priority value (nonzero) does not take
effect, even though it appears that it is from QCS.
