As Linus says: "Documentation is always wrong." Daniel discovered
it just recently. The problem is that my percent computation code
is now wrong. For fixing it  I have done measurements with five ZD1211
devices. This time I want to make sure it is right. Patches will
be available over the next few days.

If you want to recheck status->signal_strength directly, use this
simple patch:

diff --git a/zd_mac.h b/zd_mac.h
index ecf1f78..6e390ff 100644
