can: netlink: Add CAN_CTRLMODE_PRESUME_ACK flag

2014-07-15T07:34:19+00:00

Most CAN controllers have a support for ignoring ACK absence. Some of
them refer to this feature as a self test mode (e. g. SJA1000) and some
include it as a part of a loopback mode (e. g. MCP2510).

Setting the introduced flag via netlink should make CAN controller
perform a successful transmission, even if there is no acknowledgement
(dominant ACK bit) received.

can: unify identifiers to ensure unique include processing

2014-05-19T07:38:24+00:00

Armin pointed me to the fact that the identifier which is used to ensure the
unique include processing in lunux/include/uapi/linux/can.h is CAN_H.
This clashed with his own source as includes from libraries and APIs should
use an underscore '_' at the identifier start.

This patch fixes the protection identifiers in all CAN relavant includes.

can: allow to change the device mtu for CAN FD capable devices

2014-03-07T08:18:23+00:00

The configuration for CAN FD depends on CAN_CTRLMODE_FD enabled in the driver
specific ctrlmode_supported capabilities.

The configuration can be done either with the 'fd { on | off }' option in the
'ip' tool from iproute2 or by setting the CAN netdevice MTU to CAN_MTU (16) or
to CANFD_MTU (72).

can: introduce the data bitrate configuration for CAN FD

2014-03-07T08:18:22+00:00

As CAN FD offers a second bitrate for the data section of the CAN frame the
infrastructure for storing and configuring this second bitrate is introduced.
Improved the readability of the if-statement by inserting some newlines.

can: add explicit copyrights to can's netlink header

2013-09-21T13:43:12+00:00

This file is copied to the source code of user space applications (in
this case can-utils) and so it makes sense to mention explicitly their
copyright.

can: gw: add a per rule limitation of frame hops

2013-08-29T20:58:24+00:00

Usually the received CAN frames can be processed/routed as much as 'max_hops'
times (which is given at module load time of the can-gw module).
Introduce a new configuration option to reduce the number of possible hops
for a specific gateway rule to a value smaller then max_hops.

Introduce new configuration flag CGW_FLAGS_CAN_IIF_TX_OK to configure if a
CAN sk_buff that has been routed with can-gw is allowed to be send back to
the originating CAN interface.
