I think you would need to iterate over all interfaces and find the one
which has the vclock, and then get the index of its real PHC.

I'm not sure to what exactly you are referring to, but in the patches
I sent we need to know whether it's a virtual clock in order to bind
the sockets.

With the jbod option each port can have a different PHC.

Ok.
