stacktrace is like:
eth_ena_pci_probe
rte_eth_dev_pci_generic_probe
rte_eth_dev_pci_allocate
rte_eth_copy_pci_info
eth_ena_dev_init
So, before eth_ena_dev_init() called, rte_eth_copy_pci_info() already should be
called and eth_dev updated with pci_dev info. And you shouldn't need this patch.
Do you observe any missing data in eth_dev?
