Yes
iwl3945: I iwl3945_tx_skb fc: 8<3>
iwl3945: I iwl3945_tx_skb mode: 2<3>
iwl3945: I iwl3945_tx_skb assoc_id: 0<3>
iwl3945: I iwl3945_tx_skb Dropping - !iwl3945_is_associated
My changes
IWL_DEBUG_DROP("fc: %d\n", fc);
IWL_DEBUG_DROP("mode: %d\n", priv->iw_mode);
IWL_DEBUG_DROP("assoc_id: %d\", priv->assoc_id);
if ((!iwl3945_is_associated(priv) ||
((priv->iw_mode == IEEE80211_IF_TYPE_STA) && !priv->assoc_id)) &&
((fc & IEEE80211_FCTL_FTYPE) == IEEE80211_FTYPE_DATA)) {
IWL_DEBUG_DROP("Dropping - !iwl3945_is_associated\n");
goto drop_unlock;
}
Was it right?
