.It Fn pci_find_device "pa" "func"
Find a device using a match function on all probed busses. The
argument
.Fa func
is called by
.Fn pci_find_device
to match a device. The argument
.Fa pa
is filled in if the device is matched.
.Fn pci_find_device
returns 1 if the device is matched, and zero otherwise. This function
is specifically for use by LKMs (see
.Xr lkm 4 )
and its use otherwise is strongly discouraged.
.It Fn pci_get_capability "pc" "tag" "capid" "offsetp" "valuep"
Parse the device capability list in configuration space looking for
capability
