The kernel documentation is now restructured text. Convert the SocketCAN
documentation and include it in the toplevel kernel documentation.
This patch doesn't do any content change.
All references to can.txt in the code are converted to can.rst.

This patch adds an 'if CAN...endif' Block around all CAN symbols in
net/can/Kconfig. So the 'depends on CAN' dependencies can be removed.

This patch adds a CAN Gateway/Router to route (and modify) CAN frames.
It is based on the PF_CAN core infrastructure for msg filtering and msg
sending and can optionally modify routed CAN frames on the fly.
CAN frames can *only* be routed between CAN network interfaces (one hop).
They can be modified with AND/OR/XOR/SET operations as configured by the
netlink configuration interface known e.g. from iptables. From the netlink
view this can-gw implements RTM_{NEW|DEL|GET}ROUTE for PF_CAN.
The CAN specific userspace tool to manage CAN routing entries can be found in
the CAN utils http://svn.berlios.de/wsvn/socketcan/trunk/can-utils/cangw.c
at the SocketCAN SVN on BerliOS.

This patch adds the virtual CAN bus (vcan) network driver.
The vcan device is just a loopback device for CAN frames, no
real CAN hardware is involved.

This patch adds the CAN core functionality but no protocols or drivers.
No protocol implementations are included here. They come as separate
patches. Protocol numbers are already in include/linux/can.h.
