Dispatch is a component to decide packets forward to host, DMAC or
HAXIDMA. It contains CDT standing for CPU dispatcher, HDT standing
for host dispatcher, WDE standing for descriptor engine and PLE standing
for payload engine. STF is one kind of modes, it can be used if packet
send to hardware and doesn't need release report.

These debug port information can help to clarify the reason if
packets stuck in dispatch.
