  When log level is set to 7 (INFO) these messages are still displayed
and should be set to DEBUG.

Sergio, Anatoly, David,
It is not so obvious to decide the log level. Please comment or ack.

Hi

Apologies for late reply, was away. Can't comment on other lines, but

Should people be forced to recompile DPDK with debug logs (and get all this
additional debug output) just to see why VFIO doesn't get initialized? I would
argue this message is not as serious an annoyance to warrant this change, but
maybe Keith has a different opinion.

Either way, I don't feel strongly for or against the change.

Thanks,
Anatoly

No, there is a run-time option --log-level.
The compiled max level must be set to DEBUG to be able to see this message
with debug --log-level.

Apologies, I wasn't aware of this feature. No objections then.

Thanks,
