This patchset adds the ability to link two netdevsim ports together and
forward skbs between them, similar to veth. The goal is to use netdevsim
for testing features e.g. zero copy Rx using io_uring.

This feature was tested locally on QEMU, and a selftest is included.

David Wei (3):
  netdevsim: allow two netdevsim ports to be connected
  netdevsim: forward skbs from one connected port to another
  netdevsim: add selftest for forwarding skb between connected ports

I think it there something wrong with your email client, cutting
subjects like this (all of them).

Apologies, I autoformatted my patch files before git send-email which
wrapped all lines including the subject.
