int pdc_get_initiator ( struct hardware_path hwpath,
struct pdc_initiator initiator 

pdc_get_initiator - Get the SCSI Interface Card params (SCSI ID, SDTR, SE or LVD) : fully bc.mod style path to the device. : the array to return the result into

Get the SCSI operational parameters from PDC. Needed since HPUX never used BIOS or symbios card NVRAM. Most ncr/sym cards won't have an entry and just use whatever capabilities of the card are (eg Ultra, LVD). But there are several cases where it's useful: o set SCSI id for Multi-initiator clusters, o cable too long (ie SE scsi 10Mhz won't support 6m length), o bus width exported is less than what the interface chip supports.
