Subject: mvebu: dts: enable IP checksum with jumbo frames for Armada 38x on Port0
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c4a25007cfccbf19e6481885af378bca5e681683;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mvebu: dts: enable IP checksum with jumbo frames for Armada 38x on Port0

The Ethernet controller found in the Armada 38x SoC's family support
TCP/IP checksumming with frame sizes larger than 1600 bytes, however
only on port 0.

This commit enables it by setting 'tx-csum-limit' to 9800B in
'ethernet@70000' node.
