+Subject: [RFT PATCH v1 3/3] net: smc91c111: flush packets on RCR register
+ 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.
