Please help me to understand what is fm10kvf.
I see only one fm10k driver:
% git grep 'struct eth_driver' drivers/net/fm10k/
drivers/net/fm10k/fm10k_ethdev.c:static struct eth_driver rte_pmd_fm10k = {

You can refer to below definition:
static const struct rte_pci_id pci_id_fm10k_map[] = {
#define RTE_PCI_DEV_ID_DECL_FM10K(vend, dev) { RTE_PCI_DEVICE(vend, dev) },
#define RTE_PCI_DEV_ID_DECL_FM10KVF(vend, dev) { RTE_PCI_DEVICE(vend, dev) },
#include "rte_pci_dev_ids.h"
{ .vendor_id = 0, /* sentinel */ },
};
As you can see that fm10k driver will manage 2 different types of devices, PF and VF.
We can say that there are 2 drivers under fm10k directory. The aspects that not applicable
to PF/VF will use condition check to control execution path. This makes driver can work with
PF and VF devices and reduce redundant code.

What is the issue with BSD?
Hi Mark,
I'm waiting for these small comments.
Please could you rebase your patch and fix it if needed?
