Note the following considerations for using DCB:
DCB is only supported on Intel Niantic physical NICs.
To verify whether the NIC supports DCB, issue the following command:
# dladm show-linkprop -p ntcs agent
A property value that is greater than zero (0) indicates that the NIC supports DCB.
DCB ports that are configured in DCB mode cannot be aggregated (trunk or DLMP mode).
Because DCB supports only the IEEE version of DCBX (not the CEE or CIN versions), external bridges must support the IEEE version to interoperate with Oracle Solaris DCB.
DCB supports ETS configuration and recommendation TLVs.
DCB is only supported in the eight traffic class configuration.
DCB does not support congestion notification (CN).
