The header file include/linux/pci_ids.h defines
#define PCI_CLASS_BRIDGE_OTHER 0x0680
#define PCI_CLASS_SYSTEM_DMA 0x0801
((struct pci_dev*)dev)->class
corresponds to the 3 bytes Class code in the PCI Configuration space
header -- 1B Base class, 1B Sub-class, 1B Reg-level interface.
In that case
(PCI_CLASS_BRIDGE_OTHER << 8)
is equivalent to 0x68000 (imagine the leading zero)
and
((PCI_CLASS_SYSTEM_DMA << 8) | 0x03))
is equivalent to 0x80103.
