The main purpose of this series is to report the CAN controller
capabilities. The proposed method reuses the existing struct
can_ctrlmode and thus do not need a new IFLA_CAN_* entry.

While doing so, I also realized that can_priv::ctrlmode_static could
actually be derived from the other ctrlmode fields. So I added two
extra patches to the series: one to replace that field with a function
and one to repack struct can_priv and fill the hole created after
removing can_priv::ctrlmode_priv.

Please note that the first two patches are not required by the third
one. I am just grouping everything in the same series because the
patches all revolve around the controller modes.


** Changelog **

v1 -> v2:

  - Add a first patch to replace can_priv::ctrlmode_static by the
    inline function can_get_static_ctrlmode()

  - Add a second patch to reorder the fields of struct can_priv for
    better packing (save eight bytes on x86_64 \o/)

  - Rewrite the comments of the third patch "can: netlink: report the
    CAN controller mode supported flags" (no changes on the code
    itself).
