Thanks for picking this up - indeed i had that on my todo list much too long.

Unforunately *many* things (like struct sockaddr_can) was outdated in the TeX
documentation. Also the introduction and the legal stuff and the
procfs-entries (like /proc/net/can/version or the sja1000 driver stuff) has
been changed or removed entirely. LLCF could be renamed to SocketCAN, etc.
In general i would suggest to add the API documentation to
linux/Documentation/networking/can.txt
but i was unsure if the BCM stuff better would go into
linux/Documentation/networking/can-bcm.txt
to prevent can.txt being growing too much.
Finally i would tend to add the translated BCM documentation, the timestamp
stuff and probably some more procfs details in
Documentation/networking/can.txt which is the up-to-date documentation. E.g.
chapter 4.2
http://lxr.linux.no/#linux+v2.6.35.5/Documentation/networking/can.txt#L474
has been already reserved for the BCM.
I would suggest to work on the SVN
socketcan/trunk/kernel/2.6/Documentation/networking/can.txt
until the documentation is fine to be added to mainline Linux.
Currently there's only a tiny difference, someone fixed in Mainline :-))

Would this approach be ok for you?
Tnx & best regards,
Oliver
