Description Flavio Leitner 2020-07-24 03:54:31 UTC 
Description of problem:

This bug is a request to add basic TSO support to OVS-DPDK.

What: The VMs should be able to send large TCP segments to other VMs or physical NICs to improve performance (better throughput and low CPU consumption).

Why: The NFV use-cases make use of larger TCP segments.

Acceptance criteria:

1) Run iperf3 from a virtual machine connected through vhost-user in client mode to another virtual machine also connected through vhost-user and see better throughput.

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