When using Gigabit Ethernet on boards i.MX running Windows 10 IoT Core users may experience network unstability and low latency using build W1809_1_1_0_imx-iotcore. This was fixed by increasing the size of Rx/Tx buffer in ethernet driver. Fix will be part of the next release of BSP, to apply fix to current version a patch was created. To apply patch, copy content of zip archive to appropriate location in folder structure and rebuild BSP.
