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.
---
v5:
* Fixed memory leak on error path.
* Separated nfb_eth_dev_create_for_ifc() from nfb_eth_common_probe().
* Reworked port matching to eliminate the port mask / 64b width and potential
integer overflow.
The nfb_eth_dev_create_for_ifc() is now called directly from
rte_kvargs_process().
* Renamed nfb_init_params to nfb_probe_params and updated the
nfb_eth_common_probe() header.
* Unified Rx+Tx MAC init and deinit functions to avoid code duplication.
* calloc/free is now used instead of rte_calloc in Rx+Tx MAC init/deinit.
* The return values of snprintf are now handled properly.
* The return value of Rx+Tx MAC init is now handled properly.
* The name of the struct type is now prefixed with nfb_.
* Used a consistent error handling pattern (-EINVAL instead of -1).
* Added descriptions to new struct members.
* Some commit messages have been updated with better descriptions.
