I compiled Xen for SMP and for some
strange reason I could not always get the network interface connected to
the backend - same for the TPM frontend and probably also block frontend.
The attached patch fixes this problem for all three drivers by explicitly
setting the requested port for the channel to 0. Since the structure is
on the stack (and not declared static) all its members should be explicitly
initialized. I don't know why I did not encounter this problem on non-SMP
systems before... [[ Maybe a function requiring all necessary parameters
passed to it explicitly as parameters would be a less errro-prone solution?]]
