Archer C50v1 causing "transmit queue 0 timed out" on other devices

[Bjoern Franke]

Hi,

I have an Archer C50v1 running gluon based on "19.07-SNAPSHOT 
r11019+10-5feb0df9bb"

It seems to cause "transmit queue 0 timed out"[1] of a r8169 system. 
First I thought the r8169 nic is broken and changed the motherboard, but 
with another board with r8169 the issue is also appearing. Changing the 
switch did not help either.

Sometimes the r8169 box is completely unreachable until I power off the 
Archer C50v1.

Now I stumbled upon the mt7621 Flow Control thread and I'm just 
wondering if this issue is related.

Cheers,
Bjoern
