Hi Marc and everyone,
second version part 2, I fixed the bug I noticed for integrated m_can devices. The accounting was wrong or missing for these. I don't have the integrated hardware myself so any testing is appreciated (I only have the tcan device to test the mcan driver). Also v2 rebases on top of v6.2-rc5.
The series implements many small and bigger throughput improvements and adds rx/tx coalescing at the end.
Best, Markus
Changes in v2: - Rebased on v6.2-rc5 - Fixed missing/broken accounting for non peripheral m_can devices.
