[PATCH 0/2] can: mcp251xfd: fix ring/coalescing configuration

Posted by Marc Kleine-Budde 1 year, 4 months ago

When changing from CAN-CC to CAN-FD mode the ring and/or coalescing
parameters might be too big.

This series fixes the problem and adds a safeguard to detect broken
coalescing configuration.
