What to put or not into rte_eth_dev_info is not that clear, but recent
description from Andrew [1] makes sense to me: using more device related static
information in dev_info instead of dynamic data.

There is an option to create a new API for this, what do you think?

Can you please describe why "switch_domain" used for? In patchset only ixgbe
uses it, and that is only for assign to dev_info, it is not clear why this is
needed.

As far as I can see this is not a generic device option, but just a way to mark
a specific virtual PMD. There must be a better way to do this, I think this flag
is not good idea.
