Hi Helin,

The second solution seems better because more integrated and automatic.
But I would like to have some EAL functions to access to PCI configuration.
These functions would have Linux and BSD implementations.
Then the PMD could change the configuration if it's allowed by a run-time
option and would notify the change with a warning/log.

Thanks for keeping us notified of your progress.
