8 | The SOFT_RST or RXEN in the control register can be used as a condition | ||
9 | to unblock the net layer via can_receive(). So check for possible | ||
10 | flushes on RCR changes. This will drop all pending packets on soft | ||
11 | reset or disable which is the functional intent of the can_receive() | ||
12 | logic. | ||
