[FS#294] linksys 1200ac (and most likely other mvneta) has a multi-flow lockout problem

[LEDE Bugs]

A new Flyspray task has been opened.  Details are below. 

User who did this - Dave Täht (dtaht) 

Attached to Project - LEDE Project
Summary - linksys 1200ac (and most likely other mvneta) has a multi-flow lockout problem
Task Type - Bug Report
Category - Kernel
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Medium
Priority - Very Low
Reported Version - Trunk
Due in Version - Undecided
Due Date - Undecided
Details - Supply the following if possible:
 - Device problem occurs on:

linksys 1200ac

 - Software versions of LEDE release, packages, etc.

Reboot (HEAD, r2246)


 - Steps to reproduce

 
Install netperf

and then, from another machine, either:

netperf -H the_device -l 60 -t TCP_MAERTS &
  netperf -H the_device -l 60 -t TCP_MAERTS &
  netperf -H the_device -l 60 -t TCP_MAERTS &
  netperf -H the_device -l 60 -t TCP_MAERTS &
  
or: 

flent -H the_device --test-parameter=download_streams=12 tcp_ndown

The result generally is that you only get one of the flows going, the others starve completely.

I am under the impression that fixes for this arrived in mainline linux (also adding BQL support)
