Description Flavio Leitner 2020-07-24 04:08:49 UTC 
Description of problem:

This bug is a request to support VMs with TSO either disabled or unsupported simultaneously with other VMs with TSO enabled.

What: The VMs supporting TSO should be able to communicate with other VMs with or without TSO support.

Why: The NFV use-cases make use of larger TCP segments, but not all VMs might support TSO.

VMs should be able to start with TSO disabled or disable TSO at runtime.

 

Acceptance criteria:

1) Run iperf3 from a virtual machine with TSO enabled connected through vhost-user in client mode to another virtual machine without TSO support also connected through vhost-user.

2) Run iperf3 from a virtual machine with TSO enabled connected through vhost-user in client mode to another physical host and see better throughput.

3) Run iperf3 from a virtual machine without TSO enabled connected through vhost-user in client mode to another physical host.
