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

["\"Scott.Jhuang (莊清翔) : 6309\"" <Scott.Jhuang@cas-well.com>]

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 Sy Jong,

But...I am programming a driver now, have any sample driver I can reference?

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,



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?
