By not scheduling the TX/RX completion worker threads when Radio is disabled, or hardware has been unplugged, the queues cannot be completely cleaned. This causes crashes when the hardware has been unplugged while the radio is still enabled. Signed-off-by:

Legacy driver uses 0xff as the second argument for the MCU_SLEEP command. It is still unknown what the values actually mean, but this will at least keep the command in-sync with the original driver. Signed-off-by:

Implement a basic flush callback function, which simply loops over all TX queues and waits until all frames have been transmitted and the status reports have been gathered. At this moment we don't support dropping any frames during the flush, but mac80211 will only send 'false' for this argument anyway, so this is not important at this time. Signed-off-by:

When the TX status handler failed to clear the queue in rt2x00usb_watchdog_tx_dma() we shouldn't use a failsave to use the rt2x00usb txdone handler. If a driver has overriden the txdone handler it must make sure the txdone handler is capable of cleaning up the queue itself. Signed-off-by:

When rt2x00 is compiled with debugging but frame dumping is currently not active we can avoid the call to do_gettimeofday. Furthermore, frame dumping is not the default case, mark it as unlikely. Signed-off-by:

The tx descriptor values qid, cw_min, cw_max and aifs are directly accessible through the tx entry struct. So there's no need to copy them into the tx descriptor and passing them to the indiviual drivers. Instead we can just get the correct value from the tx entry. Signed-off-by:

At least some devices need such a long time to inititalize WPDMA. This only increases the maximum wait time and shouldn't affect devices that have been working before. Reported-by:

All rt2x00 devices used the same Tx and Rx ring size (24 entries) till now. Newer devices (like rt2800) can however make use of a larger TX and RX ring due to 11n capabilities (AMPDUs of size 64 for example). Hence, bring rt2x00 in sync with the legacy drivers and use the same TX and RX ring sizes. Also remove the global defines RX_ENTRIES, TX_ENTRIES, BEACON_ENTRIES and ATIM_ENTRIES and use per driver values. That is 24 entries for rt2400pci, 32 entries for rt2500pci, rt2500usb, rt61pci and rt73usb and 128 (RX) and 64 (TX) for rt2800pci and rt2800usb. Signed-off-by:

Remove the magic value initialisation of the TXOP_CTRL_CFG register by defining its fields and using them during intialisation. The field RESERVED_TRUN_EN is referred to as reserved, however it is set to 1 by the legacy drivers. Hence, do the same. Signed-off-by:

The current ath9k tx queue handling code showed a few issues that could lead to locking issues, tx stalls due to stopped queues, and maybe even DMA issues. The main source of these issues is that in some places the queue is selected via skb queue mapping in places where this mapping may no longer be valid. One such place is when data frames are transmitted via the CAB queue (for powersave buffered frames). This is made even worse by a lookup WMM AC values from the assigned tx queue (which is undefined for the CAB queue). This messed up the pending frame counting, which in turn caused issues with queues getting stopped, but not woken again. To fix these issues, this patch removes an unnecessary abstraction separating a driver internal queue number from the skb queue number (not to be confused with the hardware queue number). It seems that this abstraction may have been necessary because of tx queue preinitialization from the initvals. This patch avoids breakage here by pushing the software <-> hardware queue mapping to the function that assigns the tx queues and redefining the WMM AC definitions to match the numbers used by mac80211 (also affects ath9k_htc). To ensure consistency wrt. pending frame count tracking, these counters are moved to the ath_txq struct, updated with the txq lock held, but only where the tx queue selected by the skb queue map actually matches the tx queue used by the driver for the frame.

The Mandriva patch seems to stem from 2.6.14, so much for their upstreaming effort. Didn't find another Linux reference of it, just an omnious "USB\VID_1044&PID_8004" from GigabyteZD1201U.INF for Gigabyte GN-WLBZ101 802.11b USB Adapter, which matches the Mandriva patch comment. Aboves file also lists an "USB\VID_1044&PID_8006", which I have kept appart as this "Gigabyte GN-WBZB-M 802.11b USB Adapter" didn't show up in googling. Signed-off-by:

Current 8187B initialization misses anaparam registers restore after 8187 reset. This causes ANAPARAM register to stay zeroed out (ANAPARAM2 kept its value on my tests). To avoid this, call rtl8187_set_anaparam right after chip reset (to be on the safe side, as it makes sure we restore all ANAPARAM registers). Signed-off-by:

Usually you set RTL818X_CONFIG3_ANAPARAM_WRITE when you are going to change/write ANAPARAM registers. But in current initialization of RTL8187B there is a place where ANAPARAM_WRITE bit is set without any ANAPARAM register being written, without reason, so remove it. Signed-off-by:

The GNTSel bit should only concern pci devices by looking at RTL8180 spec, which is not the case of 8187B. Also testing shows that trying to set this bit fails, a subsequent read from the register after trying to set it shows that the bit isn't set, seems the hardware ignores it, which makes sense. This setting was a left over from Realtek sources. Signed-off-by:

We were using wrong address for BRSR (Basic Rate Set Register) while initializing its value, comparing with Realtek sources, for 8187B case. Also, the same register is initialized in rtl8187b_reg_table, so remove the duplicate initialization from the table. Signed-off-by:

AP firmware uses xmitcontrol to differentiate between AMPDU and non-AMPDU frames. As the support for AMPDU is not yet added, set xmitcontrol to non-AMPDU for all tx frames for AP firmware. This field will be set to indicate ampdu/non-ampdu frames when tx AMPDU support is added. Signed-off-by:

This patch fixes a possible lengthy stall if the device is operating as an experimental 11n AP and an STA [during heavy txrx action] suddenly signalized to go off-channel (old NetworkManager), or (sleep - which is unlikely, because then it wouldn't be *active* at all!?). Because the driver has to manage the BA Window, the sudden PSM transition can leave active uplink BA sessions to the STA in a bad state and a proper cleanup is needed. Signed-off-by:

RX Stress tests of unidirectional bulk traffic with bitrates of up to 220Mbit/s have revealed that the fatal-event recovery logic [which was solely triggered by an out-of-rx-buffer situation] is too aggressive. The new method now "pings" the device and then decides - based on the response - whenever a restart is needed or not. Signed-off-by:

This patch imports all shared header changes from carl9170fw.git. * add some strategic __aligned(4). This allows the compiler generate optimized code for architectures which can't access (unaligned/packed) data efficiently. ("ath9k_hw: optimize all descriptor access functions") * add a forgotten __CARL9170FW__ ifdef around a private firmware-internal struct. * GET_VAL macro helper Very useful for extracting data out of the bit-packed PHY registers. * cosmetic changes e.g.: _CCA_MINCCA_ to just _CCA_MIN_. * version bump 1.8.8.3 -> 1.9.0.

Clearing the per packet TX AGC for the RTL8187B device appears to increase its overall TX power. This allows the device to associate and a connection to be established using APs a little further away. This is in accordance to what is done for RTL8187L devices and also what Realtek drivers do.

Check the state of the interface on op_* function so we don't try to access the hardware in when its off. The mac80211 may call these in some corner cases related, for instance, to the hardware recovery procedure. These accesses cause a kernel crash on at least some SDIO devices, because the bus is not properly claimed in that scenario. Signed-off-by:

The wl1271_rx function loops through packets in an aggregated buffer. Each packet in the buffer is handled by a call to wl1271_rx_handle_data, which will fail if skb memory allocation fails or production mode is enabled. These failures currently prevent the rx counters to be incremented, thus causing the rx loop to run forever. Fix this by ignoring error codes reported wl1271_rx_handle_data function. This essentially means that frames will be dropped in production mode, which is the intetion, and frames will be dropped if memory allocation fails, which is a decent way to recover from that situation.
