Qcom documents suggest passing of negative values to the dump command.
Currently we convert from string to u32 not s32, so we cannot pass a two's
complement value to the firmware in this way.
There is in fact only one parameter which takes a two's complement value
<tigger threshold> in the antenna diversity switch command.
Downstream:
iwpriv wlan0 dump 71 3 <schedule period> <trigger threshold> <hysteresis>
Upstream:
echo "71 3 50 -60 3" > /sys/kernel/debug/ieee80211/phy0/wcn36xx/dump
Meaning enable Antenna Diveristy Switching every 50 beacons if the signal
quality is -60db or worse and a hysteresis of 3 db or better to switch from
one antenna to another.
