How to replace the existing driver with yours?

[otschek]

Hi,

I've got several rx-overrun-problems with a MCP2515 board connected to a Raspberry Pi 3 B+.

I've read a lot about this. For example:
https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=19489
https://www.raspberrypi.org/forums/viewtopic.php?t=141052

I wonder that the problem still occurs. Isn't the low latency patch not part of the kernel? I'm using the latest Raspian in headless mode:
pi@raspberrypi:~ $ uname -a
Linux raspberrypi 5.10.17-v7+ #1403 SMP Mon Feb 22 11:29:51 GMT 2021 armv7l GNU/Linux

could you please write a short tutorial how to replace the existing MCP251x driver witht yours?

Thank you!
