Subject: [mac80211] UAPSD: WLAN_STA_PS flag cleared prematurely?
Date: Fri, 16 Mar 2012 10:26:47 +0100 [thread overview]
Message-ID: <4F630757.6070901@etit.tu-chemnitz.de> (raw)
Hi all,
in sta_info.c : ieee80211_sta_ps_deliver_response the
IEEE80211_TX_STATUS_EOSP is set for all to-be-sent frames, not only for
the last. But only the last buffered frame actually gets the EOSP flag.
/* set EOSP for the frame */
if (reason == IEEE80211_FRAME_RELEASE_UAPSD &&
qoshdr && skb_queue_empty(&frames))
*qoshdr |= IEEE80211_QOS_CTL_EOSP;
info->flags |= IEEE80211_TX_STATUS_EOSP |
IEEE80211_TX_CTL_REQ_TX_STATUS;
Consequence is, that the WLAN_STA_SP flag gets cleared (multiple times)
in ieee80211_tx_status before the last frame with EOSP has been sent.
Is this correct?
Regards,
Marco
