IIRC, the TP Scale stuff dates back to the previous NICs which (reportedly, from madwifi list/tickets) didn't implement TPC right, or Madwifi never ran TPC correctly on them. So instead of per-packet TPC being done as driven by the net80211 stack (which I bet would be needed for hostap mode, to use per-node TX power levels), it was likely done as a way for STA's to select a power limit, and maybe for coarse grained hostap operation (ie, if all STA's are close, use a lower TPC scale.) I bet Sam would know why. I agree with Felix; nothing in ath9k/mac80211 currently uses it, so why keep it around. All of the ath9k supported NICs should implement correct per-packet TPC anyway, right?
