Occasionally, the device will send interrupts while it is resuming, at a point where we are not set up again to handle them. This causes the core IRQ handling to completely disable the IRQ, and then the driver won't work again until it is reloaded/rebound. To fix this issue disable the IRQ on suspend, this will cause us to only get interrupts again after we've setup everything on resume. Signed-off-by:

For some reason, WoWLAN doesn't always seem to be happy with more advanced LQ commands. Since we don't need them as we're not going to send a lot of data, simply program the station with the very simple default LQ command. Signed-off-by:

802.11 says: "Sequence numbers for QoS (+)Null frames may be set to any value." However, if we use the normal counters then peers will get confused with aggregation since there'll be holes in the sequence number sequence. To avoid that, don't assign sequence numbers to QoS Null frames. Signed-off-by:

Updating the beacon every time right after one was transmitted is pointless, most of the time we might not even have to update it. We will update it every time it changes, which includes from set_tim(), a callback iwlwifi didn't implement so far. This also reduces latency for clients, previously we would update the beacon right after the previous one was transmitted, and then a TIM change would only take effect after that again -- updating the beacon right after the TIM changes makes the TIM change go out to the air faster.

The commit "ath9k_hw: Fix incorrect key_miss handling" changed the code to only report key miss errors if a MIC error wasn't reported. When checking the flags in that order in the MAC code, it might miss some real events, because the value of the MIC error flag is undefined under some conditions. The primary issue addressed by the previous commit is making sure that MIC errors are properly reported on the STA side. This can be fixed in a better way by adding a separate rx status flag for key miss and ignoring it for multicast frames. This fix slightly improves stability in AP mode on some older hardware, like AR9132. Signed-off-by:

The code for handling various restrictions concerning regulatory limits, antenna gain, etc. is very convoluted and duplicated across various EEPROM parsing implementations, making it hard to review. This patch partially cleans up the mess by unifying regulatory limit handling in one function and simplifying handling of antenna gain. It also removes unused transmit power scaling arrays from the EEPROM code, which belonged to an unimplemented API that isn't supposed to be in the driver anyway. Signed-off-by:

PHY errors relevant for ANI are always tracked by hardware counters, the bits that allow them to pass through the rx filter are independent of that. Enabling PHY errors in the rx filter often creates lots of useless DMA traffic and might be responsible for some of the rx dma stop failure warnings. Signed-off-by:

This was another workaround for truesize "bugs". The reason we did this was that when we orphaned the SKB it wouldn't be truesize-checked later. Now that the check is gone (and we just charge the former smaller size to the socket) there's no longer a reason to orphan the skb here. Keep the skb charged to the socket until it is really freed (or orphaned in TX status). This helps flow control and allows us to get at the socket later for other purposes. Signed-off-by:

There's no need to adjust truesize. The history of this was that we always ran into skb_truesize_bug (via skb_truesize_check) which has since been removed in commit 92a0acce. skb_truesize_check() checked that truesize was bigger or equal to the actual allocation, which would trigger in mac80211 due to header adding. The check no longer exists and we shouldn't be messing with the truesize anwyay. Signed-off-by:

We can now move the radiotap header parsing into ieee80211_monitor_start_xmit(). This moves it out of the hotpath, and also helps the code since now the radiotap header will no longer be present in ieee80211_xmit() etc. which is easier to understand. Signed-off-by:

The purpose of this is two-fold: 1) by moving it out of tx_data.flags, we can in another patch move the radiotap parsing so it no longer is in the hotpath 2) if a device implements fragmentation but can optionally skip it, the radiotap request for not doing fragmentation may be honoured Signed-off-by: -

Since the only way the interface can be a monitor interface in ieee80211_xmit() is because the frame came from ieee80211_monitor_start_xmit() we can move all the code there. Signed-off-by:

Do not increment the retry counter if packets to a sleeping station were not sent because of tx failure, instead of only checking the filter flag. Clear the PS filter only after an A-MPDU was reported as filtered, otherwise the hardware might do some unnecessary extra retransmissions. Signed-off-by:

If "axq_qnum >= ARRAY_SIZE(sc->tx.txq)", then the call to ath9k_hw_releasetxqueue() would read beyond the end of the ah->txq[] array and possibly corrupt memory. Fortunately, ath9k_hw_setuptxqueue() doesn't return high values of "axq_qnum" and this code can be removed. Signed-off-by:

th5k_hw_setup_tx_queue() returns a valid offset into the ah->ah_txq[] array. The ah->ah_txq[] and the ah->txqs[] array are the same size. Both have AR5K_NUM_TX_QUEUES elements. So this error handling code will never trigger. Also it's wrong. The call to ath5k_hw_release_tx_queue() with a qnum of AR5K_NUM_TX_QUEUES or more will just trigger a WARN_ON() and return. Or if it missed the WARN_ON(), it would just corrupt some memory and return. Signed-off-by:
