For a better review here is the complete series of available patches with
some changes, especially the error-signalling handling.

The changes to Vincents original patches are documented below:

Oliver Hartkopp (2):
  can: dev: can_dev_dropped_skb: drop CC/FD frames in CANXL-only mode
  (replaces can: netlink: add CAN_CTRLMODE_XL_ERR_SIGNAL flag patch)
  can: raw: instantly reject unsupported CAN frames
  (the adapted version using can_dev_in_xl_only_mode() helper)

Vincent Mailhol (13):
  can: bittiming: apply NL_SET_ERR_MSG() to can_calc_bittiming()
  (no change)
  can: dev: can_dev_dropped_skb: drop CAN FD skbs if FD is off
  (no change)
  can: netlink: add CAN_CTRLMODE_RESTRICTED
  (no change)
  can: netlink: add initial CAN XL support
  (remove the "bad device" warning for CAN_CTRLMODE_RESTRICTED)
  can: netlink: add CAN_CTRLMODE_XL_TMS flag
  (remove the requirement that TMS MUST be set. Use defaults: off)
  can: bittiming: add PWM parameters
  (no change)
  can: bittiming: add PWM validation
  (no change)
  can: calc_bittiming: add PWM calculation
  (no change)
  can: netlink: add PWM netlink interface
  (no change)
  can: calc_bittiming: get rid of the incorrect "nominal" word
  (no change)
  can: calc_bittiming: add can_calc_sample_point_nrz()
  (no change)
  can: calc_bittiming: add can_calc_sample_point_pwm()
  (no change)
