test of using Onload to accelerate the vmxnet3 virtual network adapter in a VMware virtual machine...

[density1970]

Has there been any testing of using Onload to accelerate the vmxnet3 virtual network adapter in a VMware virtual machine (Ubuntu 22.04.1) environment? Based on testing, vmxnet3 does not natively support AF_XDP, and ntuple-filters are defaulted to "off" and are fixed, meaning they cannot be modified by the virtual machine itself. The compilation and usage process is as follows:

onload_build & onload_install: Use the --no-sfc parameter.

onload_tool reload: Use the --onload-only parameter.

make -C ./src/tools/bpf_link_helper/

echo $(realpath ./src/tools/bpf_link_helper/bpf-link-helper) | sudo tee /sys/module/sfc_resource/parameters/bpf_link_helper

echo ens160 > /sys/module/sfc_resource/afxdp/register

After starting my socket application, there is no data traffic between the remote server and the application.
