3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felix Fietkau <nbd@openwrt.org>
commit a3d63cadbad97671d740a9698acc2c95d1ca6e79 upstream.
RSSI is being stored internally as s8 in several places. The indication of an unset RSSI value, ATH_RSSI_DUMMY_MARKER, was supposed to have been set to 127, but ended up being set to 0x127 because of a code cleanup mistake. This could lead to invalid signal strength values in a few places.
