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
