Subject: [PATCH v1 0/5] can: netlink: preparation before introduction of CAN XL

An RFC was sent last weekend to kick-off the discussion of the
introduction of CAN XL [1]. While the series received some positive
feedback, it is far from completion. Some work is still needed to:

  - adjust the nesting of the IFLA_CAN_XL_DATA_BITTIMING_CONST in the
    netlink interface

  - add the CAN XL PWM configuration

and this TODO list may grow if more feedback is received.

Regardless of this, the RFC started with a tree wide refactor followed
by a set of trivial patches to do some clean-up and some renaming in
preparation of the introduction of CAN XL.

This series just contains those preparation patch which were cherry
picked from the RFC and rebased on of top of linux-can-next/main:

  - the first patch group all the CAN FD parameters into a new
    structure. The plan is to reuse that same structure for CAN XL.

  - the second patch is purely cosmetic and fixes a trivial tabulation
    mistake.

  - the last three patches do some renaming: both the CAN FD and the
    CAN XL have databittiming parameters. In order not to get confused
    once CAN XL will be introduced, many symbols are modified to
    explicitly add CAN FD in their names.

The goal is to have those merged first to remove some overhead from
the netlink CAN XL main series before tacking care of the other
comments.
