Max Staudt a9cf02c6a6 can: Break loopback loop on loopback documentation
There are two sections called "Local Loopback of Sent Frames". One was
meant to link to the other, but pointed at itself instead.

Erik Flodin 924e464f4a can: add a note that RECV_OWN_MSGS frames are subject to filtering
Some parts of the documentation may lead the reader to think that the
socket's own frames are always received when CAN_RAW_RECV_OWN_MSGS is
enabled, but all frames are subject to filtering.

As explained by Marc Kleine-Budde:

On TX complete of a CAN frame it's pushed into the RX path of the
networking stack, along with the information of the originating socket.

Then the CAN frame is delivered into AF_CAN, where it is passed on to
all registered receivers depending on filters. One receiver is the
sending socket in CAN_RAW. Then in CAN_RAW the it is checked if the
sending socket has RECV_OWN_MSGS enabled.

Oliver Hartkopp 75191707c7 can: update documentation for DLC usage in Classical CAN
The extension of struct can_frame with the len8_dlc element and the
can_dlc naming issue required an update of the documentation.

Additionally introduce the term 'Classical CAN' which has been established
by CAN in Automation to separate the original CAN2.0 A/B from CAN FD.

Updated some data structures and flags.

Oliver Hartkopp 3ab4ce0d6f can: rename CAN FD related can_len2dlc and can_dlc2len helpers
The helper functions can_len2dlc and can_dlc2len are only relevant for
CAN FD data length code (DLC) conversion.

To fit the introduced can_cc_dlc2len for Classical CAN we rename:

can_dlc2len -> can_fd_dlc2len to get the payload length from the DLC
can_len2dlc -> can_fd_len2dlc to get the DLC from the payload length

Mauro Carvalho Chehab b701745097 docs: can.rst: fix a footnote reference
As stated at:
	http://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html#footnotes

A footnote should contain either a number, a reference or
an auto number, e. g.:
        [1], [#f1] or [#].

While using [*] accidentaly works for html, it fails for other
document outputs. In particular, it causes an error with LaTeX
output, causing all books after networking to not be built.

So, replace it by a valid syntax.

Robert Schwebel 7d59773945 can: migrate documentation to restructured text
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.
