What is the Linux difference between PCIE and PCI device driver?
 

When attempting to write a PCIe device driver, are there specific functions and libraries that are supposed to be used, that exist outside of the pci.h? It seems you write a PCIe device driver that same way you write a PCI device driver, except you have more configuration space registers. Do PCIe device drivers use struct pci_dev or some other special struct to achieve specific PCIe things?
