From: Ilan Peer <ilan.peer@xxxxxxxxx>
If the regulatory client EIRP PSD values advertised by an AP that is a
standard power AP or indoor standard power AP are insufficient to ensure
that regulatory client limits on total EIRP are always met for all
transmission bandwidths within the bandwidth of the AP’s BSS, the AP
shall also send a TPE element in beacon and probe response frames as
that depicts the regulatory client EIRP limit.
Add support for this.
