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.
Cheers,
Jes
