- Actually, I think this flag could just disappear.
It had been added at a time when ethdev objects could only be created
through eth_drivers.
Right now, a pci driver can create ethdev objects using
rte_eth_dev_allocate(thenameyouwant).
So I would rather propose you convert your driver from a eth_driver to a
pci_driver.
It is not that hard, you only need to allocate your own private structure
and ensure the mandatory fields are filled.
You can look at rte_eth_dev_init() to see what is needed.
- Thomas, RTE_PCI_DRV_MULTIPLE deprecation for 1.8.x ?
