[dpdk-dev] Accessing "device_id" from "rte_pci_device"

["santhosh K.S" <santhoshachar08@gmail.com>]

Hi,

I'm currently trying to migrate our old DPDK 16.11 version to 17.11 release.

For this activity, I'm able to build the 17.11 DPDK successfully. When I
try to use the new libs, I noticed that few of the struct members which we
are using in our code is moved to some other struct.

In the 16.11 version we were using "*rte_eth_dev_info_get*" API to get the
device_id information using "*rte_pci_device*" struct which was initialized
inside the rte_eth_dev_info_get() API.

But now in 17.11 "*rte_pci_device" pointer * is not initialized inside the
ret_eth_dev_inf_get() API, that is because rte_pic_device is no longer a
member of the struct "*rte_eth_dev*". Hence I'm not able to retrive the
device_id from "*pci_dev->id.device_id*"

Can anyone please point me to an example code which illustrates the same?

I've already googled and got this link
<http://doc.dpdk.org/api-17.11/examples_2ethtool_2lib_2rte_ethtool_8c-example.html#a5>.
Which unfortunately doesn't show how to extract the *device_id*.

Best Regards,
Santy
