# for priority, matching on vlans - dpctl man page is terribly out of sync with CpQD's dpctl.
# we resort to looking at their dpctl header files, utilities/dpctl.h.

#
# convenience functions:
#
# ports <switch>: list port-names to port number for a switch
# vlan <switch> <inport> <outport>: call dpctl for vlan-matching flowmod addition (high priority)
# pass <switch> <inport> <outport>: call dpctl for all-matching flowmod addition (low priority)
