netdev: replace napi_reschedule with napi_schedule

2023-10-12T00:28:06+00:00

Now that napi_schedule return a bool, we can drop napi_reschedule that does the same exact function. The function comes from a very old commit bfe13f54f502 ("ibm_emac: Convert to use napi_struct independent of struct net_device") and the purpose is actually deprecated in favour of different logic. Convert every user of napi_reschedule to napi_schedule.

can: rx-offload: add can_rx_offload_get_echo_skb_queue_tail()

2023-07-28T07:45:25+00:00

Add can_rx_offload_get_echo_skb_queue_tail(). This function addds the echo skb at the end of rx-offload the queue. This is intended for devices without timestamp support. Link: https://lore.kernel.org/all/20230718-gs_usb-rx-offload-v2-2-716e542d14d5@pengutronix.de Signed-off-by: Marc Kleine-Budde

can: rx-offload: rename rx_offload_get_echo_skb() -> can_rx_offload_get_echo_skb_queue_timestamp()

2023-07-28T07:45:24+00:00

Rename the rx_offload_get_echo_skb() function to can_rx_offload_get_echo_skb_queue_timestamp(), since it inserts the echo skb into the rx-offload queue sorted by timestamp. This is a preparation for adding can_rx_offload_get_echo_skb_queue_tail(), which adds the echo skb to the end of the queue. This is intended for devices that do not support timestamps.

can: can-dev: remove obsolete CAN LED support

2022-05-19T20:15:51+00:00

Since commit 30f3b42147ba6f ("can: mark led trigger as broken") the CAN specific LED support was disabled and marked as BROKEN. As the common LED support with CONFIG_LEDS_TRIGGER_NETDEV should do this work now the code can be removed as preparation for a CAN netdevice Kconfig rework.

can: can-dev: move to netif_napi_add_weight()

2022-05-19T20:11:28+00:00

We want to remove the weight argument from the basic version of the netif_napi_add() call. Move all the callers in drivers/net/can that pass a custom weight (i.e. not NAPI_POLL_WEIGHT or 64) to the netif_napi_add_weight() API.

can: rx-offload: rename can_rx_offload_queue_sorted() -> can_rx_offload_queue_timestamp()

2022-04-19T14:58:04+00:00

This patch renames the function can_rx_offload_queue_sorted() to can_rx_offload_queue_timestamp(). This better describes what the function does, it adds a newly RX'ed skb to the sorted queue by its timestamp.

can: do not increase rx_bytes statistics for RTR frames

2022-01-05T11:09:05+00:00

The actual payload length of the CAN Remote Transmission Request (RTR) frames is always 0, i.e. no payload is transmitted on the wire. However, those RTR frames still use the DLC to indicate the length of the requested frame. As such, net_device_stats::rx_bytes should not be increased for the RTR frames. This patch fixes all the CAN drivers.
