I'm currently trying to find this out. What I know so far, is that
you can compare "something" to
#define ARPHRD_CAN 280
to find out the interface is of type SocketCAN. As there are more of
these definitions in /usr/include/linux/if_arp.h, a generic way to get
the "type" of an interface could be added to QNetworkInterface.
Maybe someone with more Linux programming knowlegde has a hint -
libenumif surely knows it, but looks like a sledgehammer for my small
problem.
Cheers,
Andre

I haven't seen it before, at least.
In this thread, Kurt Van Dijck proposed his network interface
enumeration library [2], licensed under LGPL V3, which perfectly allows
to query all SocketCAN devices. QNetworkInterface::allInterfaces() lists
them too, but there is for now no way to find out which of them are
SocketCAN interfaces.

How hard would it be to teach QNetworkInterface how to detect CAN-iness
in the interfaces it's clearly able to enumerate ?
Eddy.
