When setting up an app to run using the uio driver, errors caused by
VFIO failures should not abruptly cause the app to fail.
Example: on a board with 8 ports bound to igb_uio module, and no VFIO
configuration, a testpmd run currently fails with:
EAL: cannot open VFIO container!
EAL: :04:
The below patch is the quickest fix I found to make my applications work again,
but I'm not sure it's the best solution. Can anyone else offer other
suggestions to improve this?

Hi all,
Now that vfio support has merged into the dpdk.org mainline, I'm seeing a
number of issues with running applications, and I'm hoping someone can explain
the observed behaviour.
I have a number of NIC ports which were working correctly yesterday and are
bound correctly to the igb_uio dr

Fully agree. The minimum is to have "TODO" comments.
And please, don't consider existing API as a reference.
We must build a convenient and robust API, and probably break
the existing one i

Joubert,
By all means, look at the existing PMDs. It also helps if you have an existing
kernel driver to use/modify (preferably BSD based). That way you can have a
baseline to compare against.
At least, that is method I used.
