From 4bc4d6013b7f5a957465a22d2c7681f19a0c3e71 Mon Sep 17 00:00:00 2001 From: Peter Geis Date: Mon, 11 Feb 2019 02:04:39 +0800 Subject: [PATCH] arm64: dts: rockchip: fix rk3328-roc-cc gmac2io stability issues This patch is a port of the fix from commit 73e42e186699 ("arm64: dts: rockchip: fix rock64 gmac2io stability issues") As per that patch, enabling thresh dma mode force disables checksuming. This is necessary as tx checksuming does not work with packets larger than 1498. The rk3328-roc-cc board exhibits tx stability issues with large packets similar to rock64's issues. This patch resolves that issue.
