NEXT_PTR indicates the offset for the next item in the capability list. If the

power-on reset configuration Host Interface bit indicates PCI then NEXT_PTR

will be null (0x00), indicating there are no further items. If the power-on reset

configuration indicates AGP then NEXT_PTR will indicate the next item’s off-

set (the AGP capability, 0x44).
