From 271a234a2359975101396916f37f3c7d347c61b8 Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Thu, 10 Sep 2015 21:24:12 -0700 Subject: [PATCH] net: smc91c111: flush packets on RCR register changes 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.
