2011-01-21iwlagn: remove reference to gen2a and gen2bWey-Yi Guy

2011-01-21iwlwifi: use mac80211 throughput triggerWey-Yi Guy
Instead of keeping track of LED blink speed in the driver, use the new mac80211 trigger and link it up with an LED classdev that we now register.

2011-01-21cfg80211: Extend channel to frequency mapping for 802.11jBruno Randolf
Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping channel numbers in the 2GHz and 5GHz band we can't map from channel to frequency without knowing the band. This is no problem as in most contexts we know the band. In places where we don't know the band (and WEXT compatibility) we assume the 2GHz band for channels below 14. This patch does not implement all channel to frequency mappings defined in 802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz channels as well as 802.11y channels have been omitted. The following drivers have been updated to reflect the API changes: iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx. The drivers have been compile-tested only.

2011-01-21rtlwifi: Fix possible NULL dereferenceJesper Juhl
In drivers/net/wireless/rtlwifi/pci.c::_rtl_pci_rx_interrupt() we call dev_alloc_skb(), which may fail and return NULL, but we do not check the returned value against NULL before dereferencing the returned pointer. This may lead to a NULL pointer dereference which means we'll crash - not good. In a separate call to dev_alloc_skb(), the debug level is changed so that the failure message will always be logged.

2011-01-19mac80211: track receiver's aggregation reorder buffer sizeJohannes Berg
The aggregation code currently doesn't implement the buffer size negotiation. It will always request a max buffer size (which is fine, if a little pointless, as the mac80211 code doesn't know and might just use 0 instead), but if the peer requests a smaller size it isn't possible to honour this request. In order to fix this, look at the buffer size in the addBA response frame, keep track of it and pass it to the driver in the ampdu_action callback when called with the IEEE80211_AMPDU_TX_OPERATIONAL action. That way the driver can limit the number of subframes in aggregates appropriately. Note that this doesn't fix any drivers apart from the addition of the new argument -- they all need to be updated separately to use this variable!

2011-01-19ath9k: Fix up hardware mode and beacons with multiple vifs.Ben Greear
When using a mixture of AP and Station interfaces, the hardware mode was using the type of the last VIF registered. Instead, we should keep track of the number of different types of vifs and set the mode accordingly. In addtion, use the vif type instead of hardware opmode when dealing with beacons. Attempt to move some of the common setup code into smaller methods so we can re-use it when changing vif mode as well as adding/deleting vifs.

2011-01-19ath9k_hw: partially revert "fix dma descriptor rx error bit parsing"Felix Fietkau
The rx error bit parsing was changed to consider PHY errors and various decryption errors separately. While correct according to the documentation, this is causing spurious decryption error reports in some situations. Fix this by restoring the original order of the checks in those places, where the errors are meant to be mutually exclusive. If a CRC error is reported, then MIC failure and decryption errors are irrelevant, and a PHY error is unlikely. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2011-01-19ath9k: reduce the likelihood of baseband hang check false positivesFelix Fietkau
Since baseband hangs are rare, but the hang check function has a high false positive rate in some situations, we need to add more reliable indicators. In AP mode we can use blocked beacon transmissions as an indicator, they should be rare enough. In station mode, we can skip the hang check entirely, since a true hang will trigger beacon loss detection, and mac80211 will rescan, which leads to a hw reset that will bring the hardware back to life. To make this more reliable, we need to skip fast channel changes if the hardware appears to be stuck. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
