NAME

pci_pcie_cap - get the saved PCIe capability offset

int pci_pcie_cap(struct pci_dev * dev);

ARGUMENTS

dev

PCI device

DESCRIPTION

PCIe capability offset is calculated at PCI device initialization time and saved in the data structure. This function returns saved PCIe capability offset. Using this instead of pci_find_capability reduces unnecessary search in the PCI configuration space. If you need to calculate PCIe capability offset from raw device for some reasons, please use pci_find_capability instead.
