2011-06-10mwifiex: get rid of global adapter pointerAmitkumar Karwar
1) Avoid global adapter pointer usage a) in sdio.c by moving some code from mwifiex_cleanup_module() to mwifiex_sdio_remove(). b) in main.c by passing an extra parameter to few functions. 2) Add new variable "user_rmmod" to identify if mwifiex_sdio_remove() callback function is called in card removal or rmmod context. These code changes are adapted from Libertas driver. 3) Remove unnecessary NULL pointer check for "func" pointer in mwifiex_sdio_remove().

2011-06-10libertas: add sd8686 reset_card supportDaniel Drake
At http://dev.laptop.org/ticket/10748 we are seeing a case of the libertas firmware randomly stopping responding to commands after resume. Careful monitoring of communications indicates a firmware or hardware bug, which has been reported to Marvell. Work around this issue by adding a reset_card method; this is automatically called when command timeouts are detected and provides an instant recovery to this situation.

2011-06-08iwlegacy: fix channel switch lockingStanislaw Gruszka
We use priv->mutex to avoid race conditions between chswitch_done() and mac_channel_switch(), when marking channel switch in progress. But chswitch_done() can be called in atomic context from rx_csa() or with mutex already taken from commit_rxon(). To fix remove mutex from chswitch_done() and use atomic bitops for marking channel switch pending.

2011-06-07mwifiex: disable transmission buffer aggregation for AMSDU packetsYogesh Ashok Powar
Padding per MSDU will affect the length of next packet and hence the exact length of next packet is uncertain here. Also, aggregation of transmission buffer, while downloading the data to the card, wont gain much on the AMSDU packets as the AMSDU packets utilizes the transmission buffer space to the maximum (adapter->tx_buf_size).

Instead of counting the number of packets in txq for particular RA list before AMSDU creation, maintain a counter which will keep track of the same. This will reduce some MIPS while generating AMSDU traffic as we only have to check the counter instead of traversing through skb list.

2011-06-06iwlagn: use cts-to-self protection on 5000 adapters seriesStanislaw Gruszka
This patch fixes 802.11n stability and performance regression we have since 2.6.35. It boost performance on my 5GHz N-only network from about 5MB/s to 8MB/s. Similar percentage boost can be observed on 2.4 GHz. These are test results of 5x downloading of approximately 700MB iso image: vanilla: 5.27 5.22 4.94 4.47 5.31 ; avr 5.0420 std 0.35110 patched: 8.07 7.95 8.06 7.99 7.96 ; avr 8.0060 std 0.055946 This was achieved with NetworkManager configured to do not perform periodical scans, by configuring constant BSSID. With periodical scans, after some time, performance downgrade to unpatched driver level, like in example below: patched: 7.40 7.61 4.28 4.37 4.80 avr 5.6920 std 1.6683 However patch still make better here, since similar test on unpatched driver make link disconnects with below messages after some time: wlan1: authenticate with 00:23:69:35:d1:3f (try 1) wlan1: authenticate with 00:23:69:35:d1:3f (try 2) wlan1: authenticate with 00:23:69:35:d1:3f (try 3) wlan1: authentication with 00:23:69:35:d1:3f timed out On 2.6.35 kernel patch helps against connection hangs with messages: iwlagn 0000:20:00.0: queue 10 stuck 3 time.
