Subject: Setting up interfaces in loopback mode using SIOCETHTOOL
Date: Tue, 16 Jun 2015 16:22:12 +0530	[thread overview]
Message-ID: <CAC4WbQYt6K8xoHxviiGSsPRoEd7UX4Rhs0wkUvF+MPHG3yU2Aw@mail.gmail.com> (raw)

Hi All,

In spite of several days of trying to get information out of ethtool
source code, I could not get a way to set the loopback mode for
network interfaces. I was also referring to the driver code for ixgbe
devices to get more info on the support it provides to ethtool. In the
driver code, there seems to be a way to set the loopback mode. But I
had no idea how to refer to this code from user space.

The SIOCETHTOOL is pretty general purpose. There is a way to test the
interface in loopback mode via the command line interface. But I just
wanted to set the interface in loopback mode so that I could send
packets on the interface myself and stress the interface.

Please help me with any suggestion in this regard.

Thanks,
----
Ashutosh
