The workaround is to disable -TX offloading with 'ethtool -K eth0 tx off rx off' causing performance -impacts as it disables hardware checksumming. - -This patch sets snps,txpbl to 0x4 which is a safe number tested ok for -the most popular MTU value of 1500. - -For reference, see https://lkml.org/lkml/2019/4/1/1382. - -Signed-off-by: Carlos de Paula <me@carlosedp.com> -Link: https://lore.kernel.org/r/20200218221040.10955-1-me@carlosedp.com -Signed-off-by: Heiko Stuebner <heiko@sntech.de> ---- - arch/arm64/boot/dts/rockchip/rk3328.dtsi | 2 ++ - arch/arm64/boot/dts/rockchip/rk3399.dtsi | 1 + - 2 files changed, 3 insertions(+) - ---- a/arch/arm64/boot/dts/rockchip/rk3328.dtsi -+++ b/arch/arm64/boot/dts/rockchip/rk3328.dtsi -@@ -857,6 +857,7 @@ - resets = <&cru SRST_GMAC2IO_A>; - reset-names = "stmmaceth"; - rockchip,grf = <&grf>; -+ snps,txpbl = <0x4>; - status = "disabled"; - }; - -@@ -878,6 +879,7 @@ - reset-names = "stmmaceth", "mac-phy"; - phy-mode = "rmii"; - phy-handle = <&phy>; -+ snps,txpbl = <0x4>; - status = "disabled"; - - mdio { ---- a/arch/arm64/boot/dts/rockchip/rk3399.dtsi -+++ b/arch/arm64/boot/dts/rockchip/rk3399.dtsi -@@ -291,6 +291,7 @@ - resets = <&cru SRST_A_GMAC>; - reset-names = "stmmaceth"; - rockchip,grf = <&grf>; -+ snps,txpbl = <0x4>; - status = "disabled"; - }; - |
