Ok, I tested this in my L2TP setup. The first ppp session setup fails
because the PPPIOCNEWUNIT ioctl returns -EEXIST. I think the problem is
the logic in ppp_create_interface(), which does the following to create
a new ppp interface:

/* Initialize the new ppp unit */
ppp->file.index = unit;
sprintf(dev->name, "ppp%d", unit);

ret = register_netdev(dev);

Looks like there is more work to do in the ppp changes.
