Low Priority Extended VC Count (LPEVCC):

Indicates the number of (extended) Virtual Channels in
addition to the default VC belonging to the low-priority VC
(LPVC) group that has the lowest priority with respect to
other VC resources in a strict-priority VC Arbitration. The
value of 0 in this field implies strict VC arbitration.
