When FIF_BCN_PRBRESP_PROMISC is not set, we enable the hardware's BSS filter so that we'll only see packets destined for our BSS. But if no STA interfaces have been configured, we would end up passing the BSSID 00:00:00:00:00:00 into the POST_SCAN command, which actually disables the hardware's BSS filter, as it's not a valid BSSID. Fix this by passing in 01:00:00:00:00:00 instead (the criterion is that the OUI part of the BSSID must be nonzero), and add comments to explain what PRE_SCAN and POST_SCAN do. Signed-off-by:

mwl8k's ->prepare_multicast() currently just enables reception of all multicast packets, which is somewhat ineffective. Fix this by either disabling all multicast RX, enabling multicast RX according to the multicast address filter table, or enabling all multicast RX, depending on whether ->prepare_multicast() was given any multicast addresses and whether the hardware multicast address filter table is large enough to fit all requested addresses.

Minor changes to the transmit quiescing logic: - Clarify the locking rules for ->tx_wait: only the holder of fw_mutex can wait for the TX path to become idle, but tx_wait itself is read and cleared by the TX reclaim tasklet under tx_lock. - Inline mwl8k_txq_busy() in its callers. - There's no need to kick the transmitter again in mwl8k_tx_wait_empty(), since it will have been kicked when the packets currently in the TX ring were added to it. - If the TX ring didn't drain in time, run mwl8k_scan_tx_ring() after reading priv->pending_pkts without dropping tx_lock in between.

PSM entries can fail (transmitting the corresponding null-func may not be heard by the AP.) Previously, this scenario was not detected, and out-of-sync between STA and AP could occur. Add retry implementation for the entries to recover from the situation. Signed-off-by:

Currently, to avoid distortions, the TX power level has been hardcoded to a low value. The value is slightly too low for good functionality, so we increase it from 7dB to 12dB. Signed-off-by:

The null-data template (nullfunc) is dependent on the BSSID of the current AP only, so it needs to be updated only when the BSSID changes. Removed excess setting of the template. Signed-off-by:

Currently it is possible to request a scan on only disabled channels, which could be problematic for some drivers. Reject such scans, and also ignore disabled channels that are given. This resuls in the scan begin/end event only including channels that are actually used. This makes the mac80211 check for disabled channels superfluous. At the same time, remove the no-IBSS check from mac80211 -- nothing says that we should not find any networks on channels that cannot be used for an IBSS, even when operating in IBSS mode.

James Grossmann [1] reported that p54 spews out confusing messages instead of preventing the mayhem from happening. the reason is that "p54: generate channel list dynamically" is not perfect. It didn't discard incomplete channel data sets and therefore p54 advertised to support them as well.

Since sometimes mac80211 queues up a scan request to only act on it later, it must be allowed to (internally) cancel a not-yet-running scan, e.g. when the interface is taken down. This condition was missing since we always checked only the local->scanning variable which isn't yet set in that situation. Reported-by:

For 6x50 series, it is wimax/wifi combo device, so driver need to enable the wimax/wifi co-exist function and send the coexist event priority table to uCode for operation. The priority table will be used by uCode to determine what is the proper action it should take when co-exist with WiMAX. For example, when WiFi runs a scan, it must own radio exclusively, therefore will disconnect WiMAX if WiMAX is connected. Signed-off-by:

Spatial Multiplexing Power Save was disabled to achieve better throughput while in power save mode by activating all the rx chains all the time. By doing so, the device power consumption is high. Enable static/dynamic spatial multiplexing power save if device support it, which can lower the power consumption without impact throughput. Signed-off-by:

This fits better in how the callbacks operate (alloc does allocation and init does initialization). This also helps if we later want to do our own initialization without relying on the mac80211 allocation. Signed-off-by:

Currently the rate scale information is pointed to from the mac80211 station structure but since that is the only member we might as well make it part of the structure. Also move the rate scaling initialization to the init function, no need to do it when we allocate the structure. This fits with how mac80211 deals with rate scaling information (it always calls init after allocation) and makes it easier for us to later call initialization directly. Signed-off-by:

Since iwlagn is the only user of these functions, move it to this module. This results in a bit more code moving than just these functions since the functions only used by them are also moved and we need to export the symbols previously available to them directly. Signed-off-by:

Handling responses to driver originated commands include passing the original command buffer to the caller. At this time it is possible for a callback to be invoked that is passed this command buffer and thus likely to access it. We need to make sure that the memory associated with that buffer is not DMA mapped at the time. Signed-off-by:

Wakeup interrupt has been updating write pointers (indexes, actually) only for tx queues 0-5. This is adequate just for 3945, but inadequate for other devices, all of which have more tx queues. Now updating all tx/command queues, so device can be aware of all new tx and host commands enqueued while device was asleep. This can potentially improve data traffic bandwidth and/or latency.

To save power, don't run apm_ops.init() until needed at "up" time. EEPROM (5000 and earlier devices) may be read without running apm_ops.init(), but OTP reads (6000 and newer devices) require a powered-up chip. Therefore, remove apm_ops.init() from the general path in XXXX_pci_probe(), and call it only if device uses OTP. Once done with OTP read, call apm_ops.stop() to reset chip and save power until "up" time comes around. NOTE: This patch depends on removal of priv->lock from iwl_apm_stop(); lock does not get initialized until later in flow. See patch "remove unneeded locks from apm_stop()". Signed-off-by:

Since priv->reg_lock was added to keep multi-access register manipulation atomic, priv->lock protection is no longer needed. Remove this from iwl_apm_stop_master() and iwl_apm_stop(). Add warning of timeout when polling for busmaster disablement confirmation, and some comments. NOTE: This is needed to enable use of apm_ops.stop() within iwl_eeprom_init(); priv->lock does not get initialized until after this flow.

This patch removes the internal command and data buffers that the GSPI driver maintained and instead relies on the Libertas core to synchronize access to the command and data ports as with the other interface drivers. This cleanup reduces the GSPI driver's memory footprint and should improve performance by removing the need to copy to these internal buffers. This also simplifies the bottom half of the interrupt handler. This is an incremental cleanup: after removing the redundant buffers, we can further improve the driver to use a threaded IRQ handler instead of maintaining its own thread. However I would like a few folks to test the buffer removal first and make sure that I'm not introducing regressions. Tested on Blackfin BF527 with DMA disabled due to an issue with the SPI host controller driver in the current bleeding-edge Blackfin kernel. I would appreciate it if someone with working DMA could test this patch and provide feedback. Signed-off-by:
