From: Dave Ertman <david.m.ertman@xxxxxxxxx>
The ice driver provides QoS information to auxiliary drivers through
the exported function ice_get_qos_params. This function doesn't
currently support L3 DSCP QoS.
Add the necessary defines, structure elements and code to support DSCP
QoS through the IIDC functions.
