From: Peter Crosthwaite To: qemu-devel@nongnu.org Cc: peter.maydell@linaro.org, richard.purdie@linuxfoundation.org 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.
