I've just realized that you are trying to fix an useless code.
Why not just remove the array rte_eth_dev_data[] at first?
We already have the array rte_eth_devices[] and there is a pointer to
rte_eth_dev_data in rte_eth_dev.
Is it just a workaround to be able to lookup the rte_eth_dev_data memzone
in the secondary process?
So wouldn't it be saner to have rte_eth_devices[] in a memzone?
Sergio, as the multi-process maintainer, I guess you have an idea :)
