network-interface and async TTY parts of the ppp driver.

+
+USING THE NEW PPP KERNEL DRIVER
+
+As of kernel version 2.3.13, the development series of kernels contain
+a new kernel PPP driver, rewritten from scratch by Paul Mackerras.
+This package supports the new driver, although it doesn't include the
+source for the new driver.
+
+The new driver is divided into two files: ppp_generic.c and
+ppp_async.c. The old ppp.c is still present in the kernel sources but
+is not used. If you compile PPP as a module, you will get two
+separate modules, called ppp_generic and ppp_async.
+
+To talk to the new driver, pppd needs to be able to open /dev/ppp,
+character device (108,0). If the special file node /dev/ppp is not
+present, pppd will create it. However, if you are running with /dev
+on a read-only filesystem, pppd will not be able to create /dev/ppp.
+In that instance you should manually create /dev/ppp using the command
+`mknod /dev/ppp c 108 0'.
+
+If you use module autoloading and have PPP as a module, you will need
+to add the following to /etc/conf.modules:
+
+alias tty-ldisc-3 ppp_async
+alias char-major-108 ppp_generic

INSTALLATION
This version of PPP has been tested on various Linux kernel versions
-(most recently 2.0.36 and 2.2.1). It will not work on kernels before
-2.0.0. If you have an earlier kernel, please upgrade to the latest 2.0
-or 2.2 kernel.

+kernel.

2. Update the kernel sources.
-If you are using a 2.2.x kernel (or a recent 2.1.x kernel), you do not
-need to do this step. If your kernel is already configured for PPP,
-then you only need to do steps 5 and 6. Otherwise, continue at step 3.
-
-If you are using a 2.0.x kernel, you need to update the kernel ppp
-driver to the version in this package. You will need a copy of the
-kernel source tree to do this. Issue the command:
+The 2.2.8 and later kernels contains the same PPP kernel driver as is
+in this release. In fact the driver in the kernel sources is slightly
+different from the one in this package as it doesn't include the stuff
+which enables the driver in this package to compile in either the 2.0
+or 2.2 kernel environment, but the two are functionally equivalent.
+If you are using a 2.2.8 or later kernel and your kernel is already
+configured for PPP, then you only need to do steps 5 and 6.
+Otherwise, continue at step 3.
+
+If you are using a 2.3 series kernel, use the kernel driver that is in
+the kernel sources. For 2.3.13 and later, this is the new driver (see
+above).
+
+If you are using a kernel earlier than 2.2.8, you can either use the
+driver in this package or upgrade your kernel to the current 2.2.x
+series kernel (2.2.12, as of the release of ppp-2.3.10). If you choose
+to use the driver in this package, you will need a copy of the kernel
+source tree to compile the driver. Issue the command:
make kernel
from the top level directory. This will install the various include
-files and source files into the proper directory for the linux
-kernel. If you don't have the kernel installed in the /usr/src/kernel
-directory then it will not work. Instead it will print a message to
-the effect that you need to specify the kernel location on the
-kinstall command.
