[PATCH 0/2] can: per-device hardware filter support

[Martin Hundebøll]

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
