That's the configured regulatory limit. There's no way for the driver to say exactly what the maximum TX power is for each configured rate for the current channel. (Or, when we eventually support per-packet TPC, what the minimum/maximum TX power range is for each peer node.) That's a nice project for someone who'd like to get more familiar with net8= 0211.
