This patch addresses concerns about efficiency of handling incoming packets. Handling of interrupts is done in a threaded interrupt handler which has a smaller latency than workqueues. This change needed a rework of the locking scheme that was much simplified. Some other (more or less longstanding) bugs are fixed: utilization of just half of the RX buffers, useless wait for interrupt on open, more reliable reset sequence. The MERR interrupt is not used anymore: it overloads the CPU in error-passive state without any additional information. One shot mode is disabled because it's not clear if it can be handled efficiently on this CAN controller.
