On the wl1271 we actually do get the value that triggered the event, but
on the wl1251, for instance, we do not get it. On the wl1271 we get to
decide the above/below on the host based on the reading, but the wl1251
will just tell the host that now the RSSI went below, and now it just
went above.
Our thinking is that the above/below information is sufficient to make a
decisions about roaming. Adding the literal value will give trouble with
HW not supporting it.
If you feel the actual value of the RSSI would be important, we could
add it as an optional field to the notifcation in addition to the
above/below.
