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).
