If the txq->axq_q is empty, the code was breaking out of the tx_processq logic without checking to see if it should transmit other queued AMPDU frames (txq->axq_acq). This patches ensures ath_txq_schedule is called. This needs review. Signed-off-by:

Previously I hacked this with an msleep(300) which was fine since we never had longer PAN time slots, but now that we will have them I need to fix that. Use the new notification wait support to properly wait for the WIPAN deactivation complete signal from the ucode. Signed-off-by:

In order to implement waiting for notifications, add a structure that captures the information, and a list of such structures that will be traversed when a command is received from the ucode. Use sparse checking to make sure calls to the prepare/wait/cancel functions are always nested correctly. Signed-off-by:

When running as a 4-addr station against an AP that has the 4-addr VLAN interface and the main 3-addr AP interface bridged together, sometimes frames originating from the station were looping back from the 3-addr AP interface, causing the bridge code to emit warnings about receiving frames with its own source address. I'm not sure why this is happening yet, but I think it's a good idea to drop all frames (except 802.1x/EAP frames) that do not match the configured addressing mode, including 4-address frames sent to a 3-address station. User test reports indicate that the problem goes away with this patch. Signed-off-by:

Currently, mac80211 always advertises that it may send up to 64 subframes in an aggregate. This is fine, since it's the max, but might as well be set to zero instead since it doesn't have any information. However, drivers might have that information, so allow them to set a variable giving it, which will then be used. The default of zero will be fine since to the peer that means we don't know and it will just use its own limit for the buffer size. Signed-off-by:

The aggregation code currently doesn't implement the buffer size negotiation. It will always request a max buffer size (which is fine, if a little pointless, as the mac80211 code doesn't know and might just use 0 instead), but if the peer requests a smaller size it isn't possible to honour this request. In order to fix this, look at the buffer size in the addBA response frame, keep track of it and pass it to the driver in the ampdu_action callback when called with the IEEE80211_AMPDU_TX_OPERATIONAL action. That way the driver can limit the number of subframes in aggregates appropriately. Note that this doesn't fix any drivers apart from the addition of the new argument -- they all need to be updated separately to use this variable! Signed-off-by:

When mesh is disabled, mac80211 was returning beacons with an empty mesh ID. That isn't desirable, even if drivers shouldn't be trying to get beacons to start with. Signed-off-by:

When using a mixture of AP and Station interfaces, the hardware mode was using the type of the last VIF registered. Instead, we should keep track of the number of different types of vifs and set the mode accordingly. In addtion, use the vif type instead of hardware opmode when dealing with beacons. Attempt to move some of the common setup code into smaller methods so we can re-use it when changing vif mode as well as adding/deleting vifs. Signed-off-by:

Because the sendbar variable was not reset to zero, the stack would send Block ACK requests for all subframes following the one that failed, which could mess up the receiver side block ack window. Signed-off-by:

Sometimes the first TID in the first AC's list is not available for forming a new aggregate (the BAW might not allow it), however other TIDs may have data available for sending. Prevent a slowdown of other TIDs by going through multiple entries until we've either hit the last one or enough AMPDUs are pending in the hardware queue. Signed-off-by:

The ath9k_hw assumes that caldata is valid only for oper channel. But with ath9k_htc case, the caldata is passed for all channels on hw_reset though we are not doing calibration on that channel. So the oper channel's nf history got cleared to default due to mismatch in channel flags. This patch also saves some space. Signed-off-by:

The rx error bit parsing was changed to consider PHY errors and various decryption errors separately. While correct according to the documentation, this is causing spurious decryption error reports in some situations. Fix this by restoring the original order of the checks in those places, where the errors are meant to be mutually exclusive. If a CRC error is reported, then MIC failure and decryption errors are irrelevant, and a PHY error is unlikely. Signed-off-by:

Some devices don't support the maximum AMDPU buffer size of 64, so we need to add an option to configure this in the hardware configuration. This value will be used in the ADDBA response instead of the value suggested in the request, if the latter is greater than the max supported. Signed-off-by:

Since baseband hangs are rare, but the hang check function has a high false positive rate in some situations, we need to add more reliable indicators. In AP mode we can use blocked beacon transmissions as an indicator, they should be rare enough. In station mode, we can skip the hang check entirely, since a true hang will trigger beacon loss detection, and mac80211 will rescan, which leads to a hw reset that will bring the hardware back to life. To make this more reliable, we need to skip fast channel changes if the hardware appears to be stuck. Signed-off-by:

txtid->seq_start may not always be up to date, when there is HT non-AMPDU traffic just before starting an AMPDU session. Relying on txtid->seq_next is better, since it is also used to generate the sequence numbers for all QoS data frames. Signed-off-by:

When a tid pointer is passed to ath_tx_send_normal(), it increases the starting sequence number for the next AMPDU action frame, which should only be done if the sequence number assignment is fresh. In this case it is clearly not. Signed-off-by:
