NAME

6       pci_pcie_cap - get the saved PCIe capability offset

SYNOPSIS

9       int pci_pcie_cap(struct pci_dev * dev);

ARGUMENTS

12       dev
13           PCI device

DESCRIPTION

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