Note the missing "up" in the flags. Since there is no device backing up
the interface, you cannot up it, as that is something the device
handles.
You probably can still create those interfaces, as that was once the
basis for the broken alias mechanism. Since this is completely
pointless, I think we should just remove that leftover, and make
creating such an interface fail.

The only known issues in the code of the BNetwork* classes already have
a TODO in the code :-)

Since 10.* is a class A network, that looks correct to me.
