lib/dim: add KUnit test for dim_calc_stats()

2026-10-02T06:52:31Z

Add a KUnit suite for the DIM library that checks the packet, byte, event and completion rates computed by dim_calc_stats(), including counter wraparound and windows whose byte or packet count times USEC_PER_MSEC does not fit in 32 bits. The latter cases fail on 32-bit architectures without the previous commit. Assisted-by: LLM Signed-off-by: Shashank Mohan Jain Signed-off-by: David S. Miller
