help
Maximum allowed DLC in a CAN frame. This parameter sets the
data buffer size in a CAN frame and is therefore only used to
optimize memory consumption.

config CAN_INIT_PRIORITY
int "CAN driver init priority"
default 80
help
CAN device driver initialization priority.
Do not mess with it unless you know what you are doing.
Note that the priority needs to be lower than the net stack
so that it can start before the networking sub-system.
config CAN_WORKQ_FRAMES_BUF_CNT

help
Number of frames in the buffer of a zcan_work.
config CAN_RX_TIMESTAMP
bool "Enable receiving timestamps"
depends on CAN_HAS_RX_TIMESTAMP
help
This option enables a timestamp value of the CAN free running timer.
The value is incremented every bit time and starts when the controller
is initialized.
config CAN_AUTO_BUS_OFF_RECOVERY
bool "Enable automatic recovery from bus-off"
default y
help
This option enables the automatic bus-off recovery according to
ISO 11898-1 (recovery after 128 occurrences of 11 consecutive
recessive bits). When this option is enabled, the recovery API is not
available.
