That's easy. Have a look at /usr/include/netgraph/atm/ng_atm.h and locate
the definition of NGM_ATM_CPCS_INIT_INFO. There you see all the applicable
paremeters to cpcsinit. 'traffic' is the traffic type - see
/usr/include/net/if_atm.h for the ATMIO_TRAFFIC_* values.
Note however, that for UBR there is no sense in specifying PCR or burst
size. Perhaps you mean VBR? If you need VBR you must use an IDT77252 based
card - the others don't support VBR.
