I have this in the code - that said, I may not be getting a pointer back ever? if (changed & BSS_CHANGED_ERP_PREAMBLE) { dev_dbg(dev, "Changed ERP_PREAMBLE: Use short preamble %i\n", bss_conf->use_short_preamble); val32 = rtl8xxxu_read32(priv, REG_RESPONSE_RATE_SET); if (bss_conf->use_short_preamble) val32 |= RSR_ACK_SHORT_PREAMBLE; else val32 &= ~RSR_ACK_SHORT_PREAMBLE; rtl8xxxu_write32(priv, REG_RESPONSE_RATE_SET, val32); rcu_read_lock(); sta = ieee80211_find_sta(vif, bss_conf->bssid); if (sta) { sta_priv = (struct rtl8xxxu_sta_priv *)sta->drv_priv; if (bss_conf->use_short_preamble) sta_priv->short_preamble = true; else sta_priv->short_preamble = false; } rcu_read_unlock(); } So what was it you were suggesting instead? I think I am confused now.
