NAME
       pci_find_next_ext_capability - Find an extended capability

SYNOPSIS
       int pci_find_next_ext_capability(struct pci_dev * dev, int start, int cap);

ARGUMENTS
       dev
           PCI device to query

       start
           address at which to start looking (0 to start at beginning of list)

       cap
           capability code

DESCRIPTION
       Returns the address of the next matching extended capability structure within the device's
       PCI configuration space or 0 if the device does not support it. Some capabilities can

       them all.
