[PATCH v2 0/8] net/nfb: rework to real multiport

This series implements real multiport for better user experience.

The existing driver creates one ethdev/port for one PCI device.
As the CESNET-NDK based cards aren't capable to represent each
Ethernet port by own PCI device, new driver implementation
processes real port configuration from firmware/card and switches
from rte_eth_dev_pci_generic_probe to multiple rte_eth_dev_create calls.

---
v2:
* Changed strcpy to strlcpy.
* Moved static array VALID_KEYS from header file.
* Fixed hex base number parsing for port argument.
* The strlcpy is used instead of strcpy.
* Used __rte_internal tag for nfb_eth_common_{probe,remove}.
* Fixed coding style and spelling issues.

Depends-on: series-37064 ("net/nfb: code cleanup")
