Date: Thu, 29 Oct 2020 09:32:14 +0100	[thread overview]
Message-ID: <20201029083218.41505-1-socketcan@hartkopp.net> (raw)

Introduce improved DLC handling for Classic CAN with introduces a new
element 'len8_dlc' to the struct can_frame and additionally rename
the 'can_dlc' element to 'len' as it represents a plain payload length.

Before implementing the CAN_CTRLMODE_CC_LEN8_DLC handling on driver level
this patch set cleans up and renames the relevant code.

No functional changes.

This patch set is based on mkl/linux-can.git (testing branch).

Changes in v2:
  - rephrase commit message of patch 4 about can_dlc replacement

Changes in v3:
  - remove unnecessarily introduced u8 cast in flexcan.c

Oliver Hartkopp (4):
  can: add optional DLC element to Classical CAN frame structure
  can: rename get_can_dlc() macro with can_get_cc_len()
  can: remove obsolete get_canfd_dlc() macro
  can: replace can_dlc as variable/element for payload length
