Instead of retrieving one packet at a time from the firmware, try to retrieve all available packets at once. This optimization decreases the number of transactions, which saves CPU cycles and increases network throughput. Signed-off-by:

The HW supports up to 4095 bytes transfers via SPI. The SPI read & write operations do not handle larger transfers, causing the HW to stall in such cases. Fix this by fragmenting large transfers into smaller chunks, and transferring each one separately. Signed-off-by:

We are integrating wl1271 commits via a new git tree now and wl1271 development should be made on top of the new tree. Update the repository url accordingly. Cc: John W. Linville <linville@tuxdriver.com> Signed-off-by: -

This patch improves connection reliability by choosing the lowest basic rate for null-func frames (which increases their range, as the firmware does not do rate fall-back for null-func frames.) Also, increase the PSM entry retry-counter. Signed-off-by:

Currently then dwell times for each channel in scans is set to an overly long value, and excessive number of probe-requests are transmitted on each channel (for active scans.) Based on testing, comparable results can be received with smaller dwell-time, and, with fever probe-requests - in fact, reducing the number of probe-requests to 2 seems to increase the number of found results. Configure more optimal values for per channel dwell times. Comparison for the different scan configurations (in my current office environment): dwell-time 60000 3x probe-req == ~60 results 40000 3x probe-req == ~50 results 30000 3x probe-req == ~40 results dwell-time 60000 2x probe-req == ~70 results 40000 2x probe-req == ~60 results 30000 2x probe-req == ~58 results The above are results for a cumulative 3 scan run. For individual scans, the number of results drop slightly more. Signed-off-by: -

Currently, the driver does not handle a failing hardware command to scan in any way - effectively, the scan machine will jam until the driver is shut down, and future scan requests will just return -EBUSY to user space, resulting in a type of busy-loop. The same problem occurs if the firmware fails to deliver the scan completion event - add timeout for this. Signed-off-by:

There is some probability of hardware failures, which currently go largely undetected. Attempt to recover from these failures by shutting down the hardware, and requesting mac80211 to reconfigure it. Signed-off-by:

The current scan implementation can jam, if the scan request ends up containing no work. This can especially happen if there is a scan request with only 11a band channels for HW that does not support 11a. Signed-off-by:

When we get no SSIDs in the scan request, we should force a passive scan in all channels. This patch adds code to force the passive scan flag to be set in that case. Signed-off-by:

In the scan state machine, the wl1271_mutex is unlocked first then relocked, and then the scan state variables are modified. This makes it possible for ieee80211_scan_complete to be called twice in some scenarios, as the scan completion event from the firmware may be processed while the mutex is unlocked. To fix the issue, move the ieee80211_scan_complete call last in the function. This is generally safer, but there still may be issues is functions calling the scan state machine rely on states checked before the unlocking of the global mutex. (forward ported from 2.6.32 -- this is not strictly needed anymore, because the mutex doesn't need to be unlocked anymore, but I'm applying this change anyway, so that the call to ieee80211_scan_complete is in the same place) Signed-off-by:

commit 8c0c709e Author: Johannes Berg <johannes@sipsolutions.net> Date: Wed Nov 25 17:46:15 2009 +0100 mac80211: move cmntr flag out of rx flags moved the CMNTR flag into the skb RX flags for some aggregation cleanups, but this was wrong since the optimisation this flag tried to make requires that it is kept across the processing of multiple interfaces -- which isn't true for flags in the skb. The patch not only broke the optimisation, it also introduced a bug: under some (common!) circumstances the flag will be set on an already freed skb! However, investigating this in more detail, I found that most of the flags that we set should be per packet, _except_ for this one, due to a-MPDU processing. Additionally, the flags used for processing (currently just this one) need to be reset before processing a new packet. Since we haven't actually seen bugs reported as a result of the wrong flags handling (which is not too surprising -- the only real bug case I can come up with is an a-MSDU contained in an a-MPDU), I'll make a different fix for rc.

Even if the reorder timeout timer fires while scanning, the frames weren't received during scanning and therefore shouldn't be dropped. To implement this, changes to the passive scan RX handler simplify understanding it, because it currently checks HW_SCANNING independently of a packet's in-scan receive status (which doesn't make a big difference, since scan_rx() will only pick up probe responses and beacons, which can't be aggregated.)

The old ieee80211_find_sta_by_hw method didn't properly find VIFS when there was more than one per AP. This caused AMPDU logic in ath9k to get the wrong VIF when trying to account for transmitted SKBs. This patch changes ieee80211_find_sta_by_hw to take a localaddr argument to distinguish between VIFs with the same AP but different local addresses. The method name is changed to ieee80211_find_sta_by_ifaddr. Signed-off-by:
