Hi all, Based on the prior discussions on hardware filtering in CAN devices[0], I've implemented such support in the m_can driver. The first patch is almost entirely identical to Oliver Hartkopp's patch from 2018[1] - I've just rebased it to v6.6 and fixed a checkpatch warning. Not sure what to do about the "Not-Signed-off-by" tag though? The second patch is new. I've tested it with a tcan4550 device together with Oliver's proof-of-concept change in iproute2[2]. Has anyone tried this approach with other devices, e.g. sja1000 ? Thanks, Martin [0] https://lore.kernel.org/linux-can/6B05F8DE-7FF3-4065-9828-530BB9C91D1B@xxxxxxxxxx/T/ [1] https://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next.git/commit/?h=can-hw-filter&id=87128f7a953ef2eef5f2d2a02ce354350e2c4f7f [2] https://marc.info/?l=linux-can&m=151949929522529 Martin Hundebøll (2): can: netlink: support setting hardware filters can: m_can: support setting hw filters drivers/net/can/dev/dev.c | 3 + drivers/net/can/dev/netlink.c | 33 ++++++++ drivers/net/can/m_can/m_can.c | 137 ++++++++++++++++++++++++++++++- include/linux/can/dev.h | 5 ++ include/uapi/linux/can/netlink.h | 1 + 5 files changed, 175 insertions(+), 4 deletions(-) -- 2.41.0
