pci_get_subdevice and pci_get_subvendor.

All the following are available:
PCI_ACCESSOR(subvendor,         SUBVENDOR,      uint16_t)
PCI_ACCESSOR(subdevice,         SUBDEVICE,      uint16_t)
PCI_ACCESSOR(vendor,            VENDOR,         uint16_t)
PCI_ACCESSOR(device,            DEVICE,         uint16_t)
PCI_ACCESSOR(devid,             DEVID,          uint32_t)
PCI_ACCESSOR(class,             CLASS,          uint8_t)
PCI_ACCESSOR(subclass,          SUBCLASS,       uint8_t)
PCI_ACCESSOR(progif,            PROGIF,         uint8_t)
PCI_ACCESSOR(revid,             REVID,          uint8_t)
PCI_ACCESSOR(intpin,            INTPIN,         uint8_t)
PCI_ACCESSOR(irq,               IRQ,            uint8_t)
PCI_ACCESSOR(domain,            DOMAIN,         uint32_t)
PCI_ACCESSOR(bus,               BUS,            uint8_t)
PCI_ACCESSOR(slot,              SLOT,           uint8_t)
PCI_ACCESSOR(function,          FUNCTION,       uint8_t)
PCI_ACCESSOR(ether,             ETHADDR,        uint8_t *)
PCI_ACCESSOR(cmdreg,            CMDREG,         uint8_t)
PCI_ACCESSOR(cachelnsz,         CACHELNSZ,      uint8_t)
PCI_ACCESSOR(mingnt,            MINGNT,         uint8_t)
PCI_ACCESSOR(maxlat,            MAXLAT,         uint8_t)
PCI_ACCESSOR(lattimer,          LATTIMER,       uint8_t)
    
Although ETHADDR is available only to cardbus cards.
