| changes |
| Date: Thu, 10 Sep 2015 21:24:12 -0700 |
| |
| The SOFT_RST or RXEN in the control register can be used as a condition |
| to unblock the net layer via can_receive(). So check for possible |
| flushes on RCR changes. This will drop all pending packets on soft |
| reset or disable which is the functional intent of the can_receive() |
| logic. |
