Yes, this may be useful in the future. But for now, I think I can
answer my question myself :)

My driver does support Netlink to set CAN link parameters. So I'll just
drop it into the CAN_NETLINK -> RX_OFFLOAD category in Kconfig, unless
anyone objects.

I just got confused because in my mind, I'm still comparing it to
slcan, whereas in reality, it's now functionally closer to all the other
hardware drivers. Netlink and all.

Apologies for the noise!
