Ubuntu – How to see whether tcp-offloading is enabled on a ubuntu server

tcp-offload-engineUbuntuvlan

I would like to find out if my Ubuntu VM uses tcp-offloading to increase the performance of VXLAN encapsulation. Where can I find this information on my machine?

NIC properties and settings are typically displayed with the ethtool command. In this case the --show-offload option may provide insightful details.

But please bear in mind that you're using a virtual server with (para-) virtualised hardware and the features a virtual network adapter shows not necessarily correspond to what is done by the hypervisor which actually controls the hardware.
