I did check in the proposed changes. uint8_t rssi moved to int8_t. Since there
are no RSSI_BASE_VALUES defined in the transceiver templates, the ed parameter
is valid from 0 to 84, 255 which means invalid is -1.
How do we shall map 255 in the future (after subtraction -91 from ed) ?
Makes +127 sense ?
B.t.w. the mainline is broken, we need to fix the IRQ handling in wibo for
RFA1.
