Subject: telefire: Make 'good' RSSI value configurable
X-Git-Tag: 1.6.0.3~79
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=e7c25e3ba04b1e9f8e6fa31e2d464fe96a074dad;hp=29edc37a8de56cb6eb028e3bf3f56aa70f109eba

telefire: Make 'good' RSSI value configurable

Different radios will have different 'good' RSSI values, so let each
product configure it, leaving the default set to -90dBm, which is
a solid signal value for the CC1111.
