Changes in v10 (2021-01-12):
  - Rebased on linux-can-next/testing and modified according to latest
    BQL patches.
Reference: https://lore.kernel.org/linux-can/[e-mail]/T/#m5f99d4da8e8934a75f9481ecc3137b59f3762413
  - Replaced __netdev_sent_queue() by netdev_sent_queue().

Changes in v9 (2021-01-09):
  - es58x_start_xmit(): do not use skb anymore after the call of
    can_put_echo_skb(). Rationale: can_put_echo_skb() calls
    skb_clone() and thus the original skb gets consumed (i.e. use
    after free issue).
  - es58x_start_xmit(): Add a "drop_skb" label to free the skb when
    errors occur.

Changes in v8 (2021-01-04):
  - The driver requires CRC16. Modified Kconfig accordingly.

Changes in v7 (2020-11-17):
  - Fix compilation issue if CONFIG_BQL is not set.
Reference: https://lkml.org/lkml/2020/11/15/163

Changes in v6 (2020-11-15):
  - Rebase the patch on the testing branch of linux-can-next.
  - Rename the helper functions according latest changes
    (e.g. can_cc_get_len() -> can_cc_dlc2len())
  - Fix comments of enum es58x_physical_layer and enum
    es58x_sync_edge.

Changes in v5 (2020-11-07):
  - Add support for DLC greater than 8.
  - All other patches from the previous series were either accepted or
    dismissed. As such, this is not a series any more but a single
    patch.

Changes in v4 (2020-10-17):
  - Remove struct es58x_abstracted_can_frame.
  - Fix formatting (spaces, comment style).
  - Transform macros into static inline functions when possible.
  - Fix the ctrlmode_supported flags in es581_4.c and removed
    misleading comments in enum es58x_samples_per_bit.
  - Rename enums according to the type.
  - Remove function es58x_can_put_echo_skb().
Reference: https://lkml.org/lkml/2020/10/10/53

Changes in v3 (2020-10-03):
  - Remove all the calls to likely() and unlikely().
Reference: https://lkml.org/lkml/2020/9/30/995

Changes in v2 (2020-09-30):
  - Fixed -W1 warnings (v1 was tested with GCC -WExtra but not with
    -W1).

v1 (2020-09-27):
 - First release
