Hi Nalla,

Can you prepare a patch as a first patch of your series, that
1) renames 'PCI_DEVID_OCTEONTX2_EP_VF' -> 'PCI_DEVID_OCTEONTX2_EP_NET_VF'
2) adds 'PCI_DEVID_OCTEONTX2_EP_RAW_VF'

And does required driver changes for above.

Since that change requires update in the existing driver, 	 'raw/octeontx2_ep', 
better to get it out of way before 'net/octeontx_ep' changes, instead of 
spreading this into the 'net/octeontx_ep' patches.

What do you think?

Below is using new log type, 'otx_net_ep_logtype', but why above two, 'info' & 
'err' types continue to use 'RTE_LOGTYPE_PMD'?
Can you switch them to new log type please?

I think you need to move 'RTE_LOG_REGISTER' into this patch, that macro creates 
the 'otx_net_ep_logtype' logtype variable. Currently that macro is in next patch.

<...>
  static int
  otx_ep_eth_dev_init(struct rte_eth_dev *eth_dev)
  {
-	RTE_SET_USED(eth_dev);
+	struct rte_pci_device *pdev = RTE_ETH_DEV_TO_PCI(eth_dev);
+	struct otx_ep_device *otx_epvf = OTX_EP_DEV(eth_dev);
+	struct rte_ether_addr vf_mac_addr;
+
+	/* Single process support */
+	if (rte_eal_process_type() != RTE_PROC_PRIMARY)
+		return 0;
+
+	otx_epvf->eth_dev = eth_dev;
+	otx_epvf->port_id = eth_dev->data->port_id;
+	eth_dev->data->mac_addrs = rte_zmalloc("otx_ep", RTE_ETHER_ADDR_LEN, 0);
+	if (eth_dev->data->mac_addrs == NULL) {
+		otx_ep_err("MAC addresses memory allocation failed\n");
+		return -ENOMEM;
+	}
+	rte_eth_random_addr(vf_mac_addr.addr_bytes);
+	rte_ether_addr_copy(eth_dev->data->mac_addrs, &vf_mac_addr);
The API is 'rte_ether_addr_copy(from, to)', _unfortunately it is reverse of the 
more standard (dst, src) order_, can parameters be used wrong above?
