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

2014-03-07T08:18:23Z

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

2014-03-07T08:18:22Z

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. Signed-off-by: Oliver Hartkopp Acked-by: Stephane Grosjean Signed-off-by: Marc Kleine-Budde

can: add ability to allocate CANFD frame in skb data

This patch adds the ability of allocating a CANFD frame data structure in the skb data area. Signed-off-by: Stephane Grosjean Acked-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde

can: export a safe netdev_priv wrapper for candev

2013-01-26T15:58:59Z

In net_device notifier calls, it was impossible to determine if a CAN device is based on candev in a safe way. This patch adds such test in order to access candev storage from within those notifiers.

can: add tx/rx LED trigger support

2013-01-26T15:58:59Z

This patch implements the functions to add two LED triggers, named -tx and -rx, to a canbus device driver. Triggers are called from specific handlers by each CAN device driver and can be disabled altogether with a Kconfig option. The implementation keeps the LED on when the interface is UP and blinks the LED on network activity at a configurable rate. This only supports can-dev based drivers, as it uses some support field in the can_priv structure. Supported drivers should call devm_can_led_init() and can_led_event() as needed. Cleanup is handled automatically by devres, so no *_exit function is needed. Supported events are: - CAN_LED_EVENT_OPEN: turn on tx/rx LEDs - CAN_LED_EVENT_STOP: turn off tx/rx LEDs - CAN_LED_EVENT_TX: trigger tx LED blink - CAN_LED_EVENT_RX: trigger tx LED blink Cc: Wolfgang Grandegger Cc: Marc Kleine-Budde Signed-off-by: Fabio Baltieri Acked-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde

can: mark bittiming_const pointer in struct can_priv as const

2012-07-20T10:31:05Z

This patch marks the bittiming_const pointer as in the struct can_pric as "const". This allows us to mark the struct can_bittiming_const in the CAN drivers as "const", too. Signed-off-by: Marc Kleine-Budde

candev: add/update helpers for CAN FD

2012-06-19T19:40:14Z

- update sanity checks - add DLC to length conversion helpers - can_dlc2len() - get data length from can_dlc with sanitized can_dlc - can_len2dlc() - map the sanitized data length to an appropriate DLC Signed-off-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde

can: dev: let can_get_echo_skb() return dlc of CAN frame

2012-02-03T00:21:25Z

can_get_echo_skb() is usually called in the TX complete handler. The stats->tx_packets and stats->tx_bytes should be updated there, too. This patch simplifies to figure out the size of the sent CAN frame. Signed-off-by: Marc Kleine-Budde

can: remove references to berlios mailinglist

2011-10-17T23:22:46Z

The BerliOS project, which currently hosts our mailinglist, will close with the end of the year. Now take the chance and remove all occurrences of the mailinglist address from the source files. Signed-off-by: Marc Kleine-Budde Signed-off-by: David S. Miller

Fix some #includes in CAN drivers (rebased for net-next-2.6)

2010-04-13T10:32:42Z

In the current implementation, CAN drivers need to #include _before_ they #include , which is both ugly and unnecessary. Fix this by including in and remove the #include lines from drivers. Signed-off-by: Hans J. Koch Signed-off-by: David S. Miller
