Issue
Currently, there exists a mechanism for establishing Stream Indexed connections between DEVs in the piconet.
However, there is currently not defined a mechanism for associating an incoming upper protocol layer SDU with a specific level of QoS and a specific Stream Indexed connection.

QoS Proposal
Defines a Service Specific Convergence Sublayer (SSCS)
Receives SDUs from upper protocol layers
Classifies received SDUs and processes the same if required.
Delivers each SSCS PDU to the correct MAC-CPS SAP.
Receives SSCS PDUs from a peer SSCS entity.

Requirements for QoS:
Default Service Flows w/ default QoS parameters.
Support for dynamic creation of custom Service Flows and their QoS parameters.
Scheduling algorithm which uses the Service Flow QoS parameters to allocate piconet resources.
