can: kvaser_pciefd: Add additional Xilinx interrupts

2024-03-19T14:26:01+00:00

Since Xilinx-based adapters now support up to eight CAN channels, the
TX interrupt mask array must have eight elements.

can: mcp251xfd: __mcp251xfd_get_berr_counter(): use CAN_BUS_OFF_THRESHOLD instead of open coding it

2024-03-04T07:47:04+00:00

Since 3f9c26210cf8 ("can: error: add definitions for the different CAN
error thresholds") we have proper defines for the various CAN error
thresholds. So make use of it and replace 256 by
CAN_BUS_OFF_THRESHOLD.

can: gs_usb: gs_cmd_reset(): use cpu_to_le32() to assign mode

2024-03-04T07:46:56+00:00

The structure gs_device_mode dm::mode is a __le32, use cpu_to_le32()
to assign GS_CAN_MODE_RESET.

As GS_CAN_MODE_RESET is 0x0, this is basically a no-op.

rtnetlink: prepare nla_put_iflink() to run under RCU

2024-02-26T11:46:12+00:00

We want to be able to run rtnl_fill_ifinfo() under RCU protection
instead of RTNL in the future.

This patch prepares dev_get_iflink() and nla_put_iflink()
to run either with RTNL or RCU held.

====================
pull-request: can-next 2024-02-20

this is a pull request of 9 patches for net-next/master.

The first patch is by Francesco Dolcini and removes a redundant check
for pm_clock_support from the m_can driver.

Martin Hundebøll contributes 3 patches to the m_can/tcan4x5x driver to
allow resume upon RX of a CAN frame.

3 patches by Srinivas Goud add support for ECC statistics to the
xilinx_can driver.

The last 2 patches are by Oliver Hartkopp and me, target the CAN RAW
protocol and fix an error in the getsockopt() for CAN-XL introduced in
the previous pull request to net-next (linux-can-next-for-6.9-20240213).
