That sounds like just a bug in testpmd that need to be fixed, no?
Any particular places where outdated device info is used?

Hm, and you create new ports inside failsafe PMD, right and then set new owner_id for it?
And all this in alarm in interrupt thread?
If so I wonder how you can guarantee that no-one else will set different owner_id between
rte_eth_dev_allocate() and rte_eth_dev_owner_set()?
Could you point me to that place (I am not really familiar with familiar with failsafe code)?

Ok, if failsafe really assigns its owner_id(s) to ports that are already in use by the app,
then how such scheme supposed to work at all?
I.E. application has a port - it assigns some owner_id != 0 to it, then PMD tries to
set its owner_id tot the same port.
Obviously failsafe's set_owner() will always fail in such case.
>From what I hear we need to introduce a concept of 'default owner id'.
I.E. when failsafe PMD is created - user assigns some owner_id to it (default).
Then failsafe PMD generates it's own owner_id and assigns it only to the ports
whose current owner_id is equal either 0 or 'default' owner_id.

When we discussed RFC of owner_id patch, I thought we all agreed that
owner_id API shouldn't be mandatory - i.e. existing apps not required to change
to work normally with that.
Though right now it seems that application changes seems necessary,
at least to work ok with failsafe PMD.
Which makes we wonder was it some sort of misunderstanding or
we did we do something wrong here?
