Hello Ushnek,
I did a review on the documentation Documentation/networking/can.txt
This section explains a bit about scope of the driver:
6.3 CAN controller hardware filters
To reduce the interrupt load on deep embedded systems some CAN
controllers support the filtering of CAN IDs or ranges of CAN IDs.
These hardware filter capabilities vary from controller to
controller and have to be identified as not feasible in a multi-user
networking approach. The use of the very controller specific
hardware filters could make sense in a very dedicated use-case, as a
filter on driver level would affect all users in the multi-user
system. The high efficient filter sets inside the PF_CAN core allow
to set different multiple filters for each socket separately.
Therefore the use of hardware filters goes to the category 'handmade
tuning on deep embedded systems'. The author is running a MPC603e
@133MHz with four SJA1000 CAN controllers from 2002 under heavy bus
load without any problems ...
Unfortunately that feature does not seems to be supported, so you won't be able to use it without modifying your driver.
You will need to study the driver code and add this feature by yourself. I guess you need to weight how much you can win in performance vs the standard usage.
Best Regards,
Ioseph
