Hello,
Having worked around the previously reported bizarre linker issues, I can now
see this new error:
PMD: virtio_dev_start(): RSS cannot be configured for VirtI/O net devices
If I want to ensure that the flows are sent consistently to the same core on
virtio-net to prevent surprises, what are my options?
Given these interfaces are probably slower than physical ones, is RX / TX from
a single core a possibility? Distributor? What are people doing to get it to
work? Is it better to use some other kind of interface like a fake virtual
Intel NIC, where the RSS might be supported, instead?
Thanks,
Matthew.
