I'm not opposed in principle to exporting this, but I have a hard time
understanding why a driver would need it.
The hashed address is a property of the constructed SAS frames, which is
done in libsas. The driver shouldn't really be calculating its own hash
instead of using what libsas provides ... or is this because the hashed
self address isn't calculated by the HBA so it needs to be programmed or
something?
