The article appears to be inaccurate. Why? AFAIK it&#x27;s possible to make use of netmap on a box with a single nic. I tried this out for myself about 2 years ago on a VMware virtual machine. How does it work? A user land packet filter can &quot;forward&quot; certain packets on to the kernel -- e.g. ssh packets in my case -- while others stick around in shared memory for kernel bypass. This means that I can ssh to the box and the ssh packets flow via the kernel, while the rest of the packets bypass the kernel, but all packets floor over the same nic. Nice :-)
