Serious question for Stephen et al, once we take this to iproute2 are we
going to be able to change the name but the string diplayed if needed?

I had a patch that called this IFLA_PARENT_ID that I was using with the
older github tree used by Jiri and Scott before these were in net-next.
I wanted to submit that as a change to what became
82f2841291cfaf4d225aa1766424280254d3e3b2, but was waiting for things to
be accepted and the dust settled.

I like the parent/child/sibling nomenclature better for 4 reasons:

- Most did not seem to like the term 'offload' since that term would be
  confusing with, GRO, GSO, etc.
- A *significant* use case for many of the high-end ASICs in datacenters
  is routing.
- switchid does not make sense in the OVS/flow case because it is all
  about flows, not switches or routers, and parent made sense there.
- I wanted to combine this for use with SR-IOV use case, so one can more
  easily map PF->VF using this.

Can you give me a bit (a day) to clean-up that patch and submit an
alternative proposal to these?
