val = pci_read_config(dev, OFFSET, len);
dev: the PCI device your driver is working on
OFFSET: the position you want to read from
len: the number of bytes you want to read
Because you specify the pci dev the system knows where to read from.
Look at any random pci driver in sys/ and it will all become clear.
