* ioconf.c.i386.patch

  Apply this patch to /sys/i386/conf/ioconf.c.i386.
  (or you just add devsw an entry such as
	%DEVSW(tun),	/* 29 = IP tunnel pseudo-device */
   Watch out for the major device number)

* files

  An example file of /sys/conf/files with tun driver.
  If you haven't modified the kernel, copying this will do.
  But if you have added other devices, you should merge this file
  with yours. All you've got to do is to add following two lines:
  -- begin --
  pseudo-device tun
  net/if_tun.c		tun needs-count always-source
  -- end --

* if_tun.c, if_tun.h

  Copy if_tun.c to /sys/net.
  Copy if_tun.h to /sys/net and /usr/include/net.
