4# The include file <bsd.kmod.mk> handles installing Kernel Loadable Device
5# drivers (KLD's).
6#
7#
8# +++ variables +++
9# CLEANFILES	Additional files to remove for the clean and cleandir targets.
10#
11# KMOD          The name of the kernel module to build.
12#
13# KMODDIR	Base path for kernel modules (see kld(4)).
14#		[${DESTKERNDIR}]
15#
16# KMODOWN	KLD owner. [${BINOWN}]
17#
18# KMODGRP	KLD group. [${BINGRP}]
19#
20# KMODMODE	KLD mode. [${BINMODE}]
21#
22# KMODLOAD	Command to load a kernel module [/sbin/kldload]
23#
24# KMODUNLOAD	Command to unload a kernel module [/sbin/kldunload]
25#
26# PROG          The name of the kernel module to build.
27#		If not supplied, ${KMOD}.o is used.
28#
29# SRCS          List of source files
30#
31# DESTKERNDIR	Change the tree where the kernel and the modules get
32#		installed. [/boot]  ${DESTDIR} changes the root of the tree
33#		pointed to by ${DESTKERNDIR}.
34#
35# MFILES	Optionally a list of interfaces used by the module.
36#		This file contains a default list of interfaces.
37#
38# FIRMWS	Firmware module in the form filename:shortname:version
39#
40# +++ targets +++
41#
42# 	install:
43#               install the kernel module and its manual pages; if the Makefile
44#               does not itself define the target install, the targets
45#               beforeinstall and afterinstall may also be used to cause
46#               actions immediately before and after the install target
47#		is executed.
48#
49# 	load:
50#		Load KLD.
51#
52# 	unload:
53#		Unload KLD.
