Looking at the current upstream driver implementation, it seems like the TX/RX flow control is enabled only if the flow control pause option is resolved from the device/link partner advertisements (or otherwise set). On the other hand, our current in-tree driver force enables TX/RX flow control by default, thus possibly leading to TX timeouts if the other end sends pause frames (which are not properly handled?): WARNING: CPU: 3 PID: 0 at net/sched/sch_generic.c:320 dev_watchdog+0x1ac/0x324 NETDEV WATCHDOG: eth0 (mtk_soc_eth): transmit queue 0 timed out Disabling the flow control on PORT 5 MAC seems to fix this issues as the pause frames are then filtered out. While at it, I'm removing the if condition completely as suggested, since this code is run only on mt7621 SoC, so there is no need to check for the silicon revisions.

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, python, 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!
