Well, you forgot to quote this from iwl-agn-rs.c:
static bool rs_use_green(struct ieee80211_sta *sta)
{
struct iwl_station_priv *sta_priv = (void *)sta->drv_priv;
struct iwl_rxon_context *ctx = sta_priv->common.ctx;
return (sta->ht_cap.cap & IEEE80211_HT_CAP_GRN_FLD) &&
!(ctx->ht.non_gf_sta_present);
}
But it looks like it's doing the right thing.
