Some rockchip SoCs like the RK3399 and RK3328 exhibit an issue where tx checksumming does not work with packets larger than 1498. The default Programmable Buffer Length for TX in these GMAC's is not suitable for MTUs higher than 1498. 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.

-----------------------------------------------------
This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
