If anyone has any objections, please let me know. ------------------ From: Oliver Hartkopp commit 81b401100c01d2357031e874689f89bd788d13cd upstream. Set in the rx_ifindex to pass the correct interface index in the case of a message timeout detection. Usually the rx_ifindex value is set at receive time. But when no CAN frame has been received the RX_TIMEOUT notification did not contain a valid value.
