Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+Some additional information for setting up a syncPPP
+connection using network interfaces.
+---------------------------------------------------------------
+
+You need one thing beside the isdn4linux package:
+
+  a patched pppd .. (I called it ipppd to show the difference)
+
+Compiling isdn4linux with sync PPP:
+-----------------------------------
+To compile isdn4linux with the sync PPP part, you have
+to answer the appropriate question when doing a "make config"
+Don't forget to load the slhc.o
+module before the isdn.o module, if VJ-compression support
+is not compiled into your kernel. (e.g if you have no PPP or
+CSLIP in the kernel)
+
+Using isdn4linux with sync PPP:
+-------------------------------
+Sync PPP is just another encapsulation for isdn4linux. The
+name to enable sync PPP encapsulation is 'syncppp' .. e.g:
+
+  /sbin/isdnctrl encap ippp0 syncppp
+
+The name of the interface is here 'ippp0'. You need 
+one interface with the name 'ippp0' to saturate the
+ipppd, which checks the ppp version via this interface.
+Currently, all devices must have the name ipppX where
+'X' is a decimal value.
+
+To set up a PPP connection you need the ipppd .. You must start 
+the ipppd once after installing the modules. The ipppd 
+communicates with the isdn4linux link-level driver using the
+/dev/ippp0 to /dev/ippp15 devices. One ipppd can handle
+all devices at once. If you want to use two PPP connections
+at the same time, you have to connect the ipppd to two
+devices .. and so on. 
+I've implemented one additional option for the ipppd:
+ 'useifip' will get (if set to not 0.0.0.0) the IP address 
+ for the negotiation from the attached network-interface. 
+(also: ipppd will try to negotiate pointopoint IP as remote IP)
+You must disable BSD-compression, this implementation can't
+handle compressed packets.
+
+Check the etc/rc.isdn.syncppp in the isdn4kernel-util package
+for an example setup script.
+
+To use the MPPP stuff, you must configure a slave device
+with isdn4linux. Now call the ipppd with the '+mp' option.
+To increase the number of links, you must use the
+'addlink' option of the isdnctrl tool. (rc.isdn.syncppp.MPPP is
+an example script)
+
+enjoy it,
