I don't know the details so it's something that would have to be
investigated.  My feeling is that if we want to deal with multiple
interfaces with LLAs we're going to need to do some not-insignificant
kernel and libc work to support them.  It not clear to me how much
overall work that will be and how worthwhile it is.
