# Formilux 0.1.8 - http://www.ant-computing.com/
# PCIDEV - PCI device drivers scanner version 0.5
# 2008/12/09 - Willy Tarreau - willy@ant-computing.com
# May be redistributed under the terms of the GPL.
#
# usage :
# pcidev [-vnm] [-c class/mask]* [path to modules.pcimap]
# examples :
# pcidev /lib/modules/`uname -r`/modules.pcimap
# pcidev -v -n -m -c 0x200000/0xffff00
#
# This program lists all pci devices, displays their IDs and the names of the
# driver attached to each device, when available, or "##none##'. If an argument
# is passed, it will be interpreted as the path to a modules.pcimap file. In
# this case, the list of all possible modules for each device is appended at
# the end of the line. If the "-n" argument is given, only modules that seem
# not to have already been loaded will be. Note that with '-n', an implicit
# path to modules.pcimap is used for the current kernel. If the "-m" argument
# is given, those modules will be loaded through modprobe (verbosely if "-v"
# is specified). "-c" limits modules to classes matching hex <class> using hex
# <mask>. Multiple -c may be used to look for multiple classes.
# Eg: -c 0x020000/0xffff00 for Ethernet devices.
