A read-write integer, 10 to 40, setting the traffic gap threshold, a percentage difference, between radios that, together with the traffic threshold, triggers load balancing for a radio, defaulting to 20. This prevents load balancing from triggering over trivial differences in traffic between radios, requiring both an absolute traffic threshold and a meaningful relative gap between radios before clients get steered, which avoids unnecessary client bouncing. With this set to 20, load balancing would only act if one radio's traffic load exceeds another's by at least a 20-point gap, in addition to crossing the traffic threshold.
