2010-02-12ath9k: add a workaround for ack timeout issuesFelix Fietkau
Adding support for setting the coverage class in some cases broke association and data transfer, as it overwrote the initial ACK timeout value from the initvals with a smaller value. I don't know why the new value works in 5 GHz (matches the initval there), but not in 2.4 GHz (initvals use 64us here), so until the problem is fully understood, the value should be increased again.

2010-02-11iwlwifi: Monitor and recover the aggregation TX flow failureTrieu 'Andrew' Nguyen
This change monitors the tx statistics to detect the drop in throughput. When the throughput drops, the ratio of the actual_ack_count and the expected_ ack_count also drops. At the same time, the aggregated ba_timeout (the number of ba timeout retries) also rises. If the actual_ack_count/expected_ack_count ratio is 0 and the number of ba timeout retries rises to 16, no tx packets (tcp, udp, or ping - icmp) can be delivered. The driver recovers from this situation by reseting the uCode firmware. If the actual_ack_count/expected_ ack_count ratio drops below 50% (but not 0) and the aggregated ba_timeout retries just exceed 5 (but not 16), then the driver can reset the radio to bring the throughput up.

2010-02-11iwlwifi: reset card during probeReinette Chatre
To ensure that card is in a sane state during probe we add a reset call. This change was prompted by users of kdump who was not able to bring up the wireless driver in the kdump kernel. The problem here was that the primary kernel, which is not running at the time, left the wireless card up and running. When the kdump kernel starts it is thus possible to immediately receive interrupts from firmware after registering interrupt, but without being ready to deal with interrupts from firmware yet.

2010-02-11iwlwifi: fix scan raceReinette Chatre
There is a problem if an "internal short scan" is in progress when a mac80211 requested scan arrives. If this new scan request arrives within the "next_scan_jiffies" period then driver will immediately return success and complete the scan. The problem here is that the scan has not been fully initialized at this time (is_internal_short_scan is still set to true because of the currently running scan), which results in the scan completion never to be sent to mac80211. At this time also, evan though the internal short scan is still running the state (is_internal_short_scan) will be set to false, so when the internal scan does complete then mac80211 will receive a scan completion. Fix this by checking right away if a scan is in progress when a scan request arrives from mac80211. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>

2010-02-08iwlwifi: Send broadcast probe request only when asked toSamuel Ortiz
When running directed active scans we currently end up sending both the SSID probe requests and an additional broadcast one. This is due to the fact that we always leave the probe request template SSID IE length to 0. Instead we should set it to the first SSID to scan, and fill the direct_scan array with the remaining SSIDs to scan for. This way we only send what we've been asked to: a broadcast probe request when no directed scan is requested, and directed probe requests otherwise.

2010-02-03b43: Fix throughput regressionLarry Finger
Commit c7ab5ef9bcd281135c21b4732c9be779585181be entitled "b43: implement short slot and basic rate handling" reduced the transmit throughput for my BCM4311 device from 18 Mb/s to 0.7 Mb/s. The basic rate handling portion is OK, the problem is in the short slot handling. Prior to this change, the short slot enable/disable routines were never called. Experimentation showed that the critical part was changing the value at offset 0x0010 in the shared memory. This is supposed to contain the 802.11 Slot Time in usec, but if it is changed from its initial value of zero, performance is destroyed. On the other hand, changing the value in the MMIO register corresponding to the Interframe Slot Time increased performance from 18 to 22 Mb/s. A BCM4306/3 also shows dramatic improvement of the transmit rate from 5.3 to 19.0 Mb/s. Other changes in the patch include removal of the magic number for the MMIO register, and allowing the slot time to be set for any PHY operating in the 2.4 GHz band. Previously, the routine was executed only for G PHYs.
