When an aggregation session is being cleaned up, while the tx status for some frames is being processed, the TID is flushed and its buffers are sent out. Unfortunately that left the pending un-acked frames unprocessed, thus leaking buffers. Fix this by reordering the code so that those frames are processed first, before the TID is flushed.

gcc complains about the firmware loading: iwl-agn.c: In function ‘iwlagn_load_firmware’: iwl-agn.c:1860: warning: ‘tlv_len’ may be used uninitialized in this function iwl-agn.c:1861: warning: ‘tlv_type’ may be used uninitialized in this function iwl-agn.c:1862: warning: ‘tlv_data’ may be used uninitialized in this function This is almost correct but we do do break out of the TLV parsing loop when setting ret. However, the code is hard to follow, and clearly even the compiler is having issues with it too. Additionally, however, the current code is wrong. If there is a TLV length check error, the code will report invalid TLV after parsing: ... because "len" will still be non-zero as we broke out of the loop. So to remove the warning and fix that issue, make the code easier to read by doing length checking with an error label. As a result, we can completely remove the "ret" variable. Also, while at it, remove the "fixed_tlv_size" variable since each TLV type has its own specified length, it just happens that we have only variable length, flags (0 length) and u32 TLVs right now. It should still be checked with more explicit length checks to make it easier to understand.

Ever since commit e1b3ec1a Author: Stanislaw Gruszka <sgruszka@redhat.com> Date: Mon Mar 29 12:18:34 2010 +0200 mac80211: explicitly disable/enable QoS mac80211 is telling drivers, in particular iwlwifi, whether QoS is enabled or not. However, this is only relevant for station mode, since only then will any device send nullfunc frames and need to know whether they should be QoS frames or not. In other modes, there are (currently) no frames the device is supposed to send. When you now consider virtual interfaces, it becomes apparent that the current mechanism is inadequate since it enables/disables QoS on a global scale, where for nullfunc frames it has to be on a per-interface scale. Due to the above considerations, we can change the way mac80211 advertises the QoS state to drivers to only ever advertise it as "off" in station mode, and make it a per-BSS setting.

An A-MPDU may contain several subframes each containing its own CRC for the data. Each subframe also has a respective CRC for the MPDU length and 4 reserved bits (aka delimeter CRC). AR9003 will ACK frames that have a valid data CRC but have failed to pass the CRC for the MPDU length, if and only if the subframe is not the last subframe in an A-MPDU and if an OFDM phy OFDM reset error has been caught. Discarding those subframes results in packet loss under heavy stress conditions, an example being UDP video. Since the frames are ACK'd by hardware we need to let these frames through and process them as valid frames.

There were a few places where the sc->rxlink pointer was set to NULL "just in case". This helps nothing - quite to the contrary it is problematic since it can create self-linked rx descriptors in the middle of the list of receive buffers. Here is an example how this could happen (thanks Bob!): cpu 0: cpu 1: ath5k_rx_stop ath5k_tasklet_rx sc->rxlink = NULL; /* just in case */ // following doesn't link used // buffer to prev. ath5k_rxbuf_setup() In the case of ath5k_rx_stop() and ath5k_stop_locked() buffers/descriptors are not changed so rxlink should not be changed as well. In ath5k_intr() we seem to try to work around a hardware bug, as the comment (which is copied 1:1 from the HAL) suggests. I don't see how this could help. Also the HAL does not set rxlink in this case (So where does this code come from? It has been there since the first import of ath5k). Changed to just increment a statistics counter. After this patch rxlink is only set to NULL before we initialize rx descriptors and updated when the descriptors are linked together.
