There are two common errors which are made when reporting the CAN RX statistics: 1. Incrementing the "normal" RX stats when receiving an Error frame. Error frames is an abstraction of Socket CAN and does not exist on the wire. 2. Counting the length of the Remote Transmission Frames (RTR). The length of an RTR frame is the length of the requested frame not the actual payload. In reality the payload of an RTR frame is always 0 bytes long. This patch series fix those two issues for all CAN drivers. Vincent Mailhol (2): can: do not increase rx statistics when receiving CAN error frames can: do not increase rx_bytes statistics for RTR frames drivers/net/can/at91_can.c | 9 ++------- drivers/net/can/c_can/c_can_main.c | 8 ++------ drivers/net/can/cc770/cc770.c | 6 ++---- drivers/net/can/dev/dev.c | 4 ---- drivers/net/can/dev/rx-offload.c | 7 +++++-- drivers/net/can/grcan.c | 3 ++- drivers/net/can/ifi_canfd/ifi_canfd.c | 8 ++------ drivers/net/can/janz-ican3.c | 3 ++- drivers/net/can/kvaser_pciefd.c | 8 ++------ drivers/net/can/m_can/m_can.c | 10 ++-------- drivers/net/can/mscan/mscan.c | 10 ++++++---- drivers/net/can/pch_can.c | 6 ++---- drivers/net/can/peak_canfd/peak_canfd.c | 7 ++----- drivers/net/can/rcar/rcar_can.c | 9 +++------ drivers/net/can/rcar/rcar_canfd.c | 7 ++----- drivers/net/can/sja1000/sja1000.c | 5 ++--- drivers/net/can/slcan.c | 3 ++- drivers/net/can/spi/hi311x.c | 3 ++- drivers/net/can/spi/mcp251x.c | 3 ++- drivers/net/can/sun4i_can.c | 10 ++++------ drivers/net/can/usb/ems_usb.c | 5 ++--- drivers/net/can/usb/esd_usb2.c | 5 ++--- drivers/net/can/usb/etas_es58x/es58x_core.c | 7 ------- .../net/can/usb/kvaser_usb/kvaser_usb_core.c | 2 -- .../net/can/usb/kvaser_usb/kvaser_usb_hydra.c | 14 ++++---------- .../net/can/usb/kvaser_usb/kvaser_usb_leaf.c | 7 ++----- drivers/net/can/usb/mcba_usb.c | 3 ++- drivers/net/can/usb/peak_usb/pcan_usb.c | 5 ++--- drivers/net/can/usb/peak_usb/pcan_usb_fd.c | 11 ++++------- drivers/net/can/usb/peak_usb/pcan_usb_pro.c | 11 +++++------ drivers/net/can/usb/ucan.c | 7 +++++-- drivers/net/can/usb/usb_8dev.c | 10 ++++------ drivers/net/can/xilinx_can.c | 17 ++++++----------- 33 files changed, 86 insertions(+), 147 deletions(-) -- 2.32.0
