Subject: [PATCH] arm64: dts: rockchip: fix rk3328-roc-cc gmac2io stability issues
Date: Mon, 11 Feb 2019 01:02:14 +0800 [thread overview]
Message-ID: <20190210170214.12057-1-pgwipeout@gmail.com> (raw)
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.
