If no "peer" is configured netdevsim is also a data sink.
We added netdevsim because dummy and veth started accumulating
"features" which were clearly just for test harnesses. Would be
great if we could stay the course and put whatever changes you
need in netdevsim, even if it requires some hacks.
Is there anything fundamentally blocking the use of netdevsim?
Or is it just convenience (since netdevsim is a bit of a PITA
to create and establish the name of)?
