[dpdk-dev] How to get net_device and use struct ethtool_cmd at DPDK enverinment?

["Scott.Jhuang (莊清翔) : 6309"]

Hi,

I want to get etherport's net_device structs and using ethtool_cmd to get some information of etherports.
Are these capabilitys igb_uio driver also provided?

If not, how can I get net_devices and use ethtool_cmd capabilitys?

Hi Scott,

You can review DPDK KNI sample app, there's ethtool support using a vEth device interfacing to DPDK PMD.

Pure DPDK PMD require programming to display the information in ethtool. The interfacing is demonstrate on KNI sample app.

Hi Scott,

You are right, the KNI will be a good reference for you. It demonstrate how DPDK PMD interface with kernel.
May I know are you planning to build the interface to ethtool? You can try running KNI app.

Re: [dpdk-dev] How to get net_device and use struct ethtool_cmd at DPDK enverinment?

["Scott.Jhuang (莊清翔) : 6309"]

Dear Sy Jong,

I'm planning to program a driver to get all the ethport's net_device structure, because I need some information from these net_device structures.
And I also need to use net_device struct's ethtool_cmd to get some information e.g. ethtool_cmd.phy_address, net_device->ethtool_ops->get_settings.

In fact, I need some information from net_device struct to access and control PHY's link-up/down,
and I reference igb driver to design the link-up/down functions, since in DPDK envirenment doesn't have igb driver,
so In DPDK envirenment, I don't know how to get network deivce's net_device structs and more information which initial by igb driver(because doesn't have igb driver).

Re: [dpdk-dev] How to get net_device and use struct ethtool_cmd at DPDK enverinment?

[Choi, Sy Jong]

Hi Scott,

DPDK PMD are interfacing using rte_ethdev.c which link to ixgbe_ethdev.c there’s no “net_device” in our code.

But if you search DPDk code based, we have KNI example to teach you how to prepare the net_device structure.
Have you check out our DPDK KNI codes?

Re: [dpdk-dev] How to get net_device and use struct ethtool_cmd at DPDK enverinment?

Hi Sy Jong,

Have any idea?

Dear Sy Jong,

Yes, I have check out DPDK KNI, but I still can't find how to prepare net_device structure...
And I also doesn't find how to get "ethtool_cmd.phy_address"
Could you let me know the path of source code folder

Hi Scott,

DPDK PMD are interfacing using rte_ethdev.c which link to ixgbe_ethdev.c there’s no “net_device” in our code.

But if you search DPDk code based, we have KNI example to teach you how to prepare the net_device structure.
Have you check out our DPDK KNI codes?

Dear Sy Jong,

I'm planning to program a driver to get all the ethport's net_device structure, because I need some information from these net_device structures.
And I also need to use net_device struct's ethtool_cmd to get some information e.g. ethtool_cmd.phy_address, net_device->ethtool_ops->get_settings.

In fact, I need some information from net_device struct to access and control PHY's link-up/down,
and I reference igb driver to design the link-up/down functions, since in DPDK envirenment doesn't have igb driver,
so In DPDK envirenment, I don't know how to get network deivce's net_device structs and more information which initial by igb driver(because doesn't have igb driver).

Hi Scott,

You are right, the KNI will be a good reference for you. It demonstrate how DPDK PMD interface with kernel.
May I know are you planning to build the interface to ethtool? You can try running KNI app.

Hi Scott,



You can review DPDK KNI sample app, there's ethtool support using a vEth device interfacing to DPDK PMD.



Pure DPDK PMD require programming to display the information in ethtool. The interfacing is demonstrate on KNI sample app.

Re: [dpdk-dev] How to get net_device and use struct ethtool_cmd at DPDK enverinment?

["Scott.Jhuang (莊清翔) : 6309"]

Hi Sy Jong,

If I load "rte_kni.ko" driver, the net_device structs will be initialled by KNI, right?
If yes, how can I handle these net_device structs in other driver,
because I using "for_each_netdev()" kernel API can't find the net_device structs which KNI initialled.
Or these structs have not been exported to kernel?

Re: [dpdk-dev] How to get net_device and use struct ethtool_cmd at DPDK enverinment?

[Choi, Sy Jong]

Hi Scott,

You will need to start KNI sample app, it will create the vEth interface. After kni app, it will be there, kni app is the datapath, it get the packet into the kernel.

http://dpdk.org/doc/guides/prog_guide/kernel_nic_interface.html


  1.  Insert the KNI kernel module:
2.  insmod ./rte_kni.ko
If using KNI in multi-thread mode, use the following command line:
insmod ./rte_kni.ko kthread_mode=multiple

  1.  Running the KNI sample application:
4.  ./kni -c -0xf0 -n 4 -- -p 0x3 -P -config="(0,4,6),(1,5,7)"
This command runs the kni sample application with two physical ports. Each port pins two forwarding cores (ingress/egress) in user space.

Hi Sy Jong,

If I load "rte_kni.ko" driver, the net_device structs will be initialled by KNI, right?
If yes, how can I handle these net_device structs in other driver,
because I using "for_each_netdev()" kernel API can't find the net_device structs which KNI initialled.
Or these structs have not been exported to kernel?

Hi Scott,

DPDK PMD are interfacing using rte_ethdev.c which link to ixgbe_ethdev.c there’s no “net_device” in our code.

But if you search DPDk code based, we have KNI example to teach you how to prepare the net_device structure.

Dear Sy Jong,

I'm planning to program a driver to get all the ethport's net_device structure, because I need some information from these net_device structures.
And I also need to use net_device struct's ethtool_cmd to get some information e.g. ethtool_cmd.phy_address, net_device->ethtool_ops->get_settings.

In fact, I need some information from net_device struct to access and control PHY's link-up/down,
and I reference igb driver to design the link-up/down functions, since in DPDK envirenment doesn't have igb driver,
so In DPDK envirenment, I don't know how to get network deivce's net_device structs and more information which initial by igb driver(because doesn't have igb driver).

You can review DPDK KNI sample app, there's ethtool support using a vEth device interfacing to DPDK PMD.



Pure DPDK PMD require programming to display the information in ethtool. The interfacing is demonstrate on KNI sample app.

Hi Sy Jong,

If I using KNI in DPDK, can I use another applications at the same time? (e.g. L2 forward, L3 forward)

Hi Scott,

You will need to start KNI sample app, it will create the vEth interface. After kni app, it will be there, kni app is the datapath, it get the packet into the kernel.

http://dpdk.org/doc/guides/prog_guide/kernel_nic_interface.html


  1.  Insert the KNI kernel module:
2.  insmod ./rte_kni.ko
If using KNI in multi-thread mode, use the following command line:
insmod ./rte_kni.ko kthread_mode=multiple

  1.  Running the KNI sample application:
4.  ./kni -c -0xf0 -n 4 -- -p 0x3 -P -config="(0,4,6),(1,5,7)"
This command runs the kni sample application with two physical ports. Each port pins two forwarding cores (ingress/egress) in user space.

Re: [dpdk-dev] How to get net_device and use struct ethtool_cmd at DPDK enverinment?

[Choi, Sy Jong]

HI Scott,

KNI app effectively will become your datapath, it is a sample app, you can modify it.
It receive packets from PMD and pass all packets to the kernel path from userspace.

You can run l2fwd, or other app, you will need to run it on other PMD ports. Not on the same ports on KNI.
Or you will need to modify KNI app, to distribute packets to kernel path or your new datapath. Basically it will be like coding  to combine kni app and l2fwd app.
