[linux-yocto] [PATCH 5/8] arm64: dts: stratix10: Support Ethernet Jumbo frame

[Meng.Li at windriver.com]

From: Thor Thayer <thor.thayer at linux.intel.com>

commit 273dce368d19982f65abe8bdced67f4218f03c06 from
https://github.com/altera-opensource/linux-socfpga.git

[backport 'commit a27460c9768e ("arm64: dts: stratix10: Support
                                 Ethernet Jumbo frame")']

Backported from net-next/master

Properly specify the RX and TX FIFO size which is important
for Jumbo frames.
Update the max-frame-size to support Jumbo frames.
