2011-01-31iwlwifi: correct frequency settingsStanislaw Gruszka1-6/+2
After commit 59eb21a6504731fc16db4cf9463065dd61093e08 "cfg80211: Extend channel to frequency mapping for 802.11j" we use uninitialized sband->band when assign channel frequencies, what results that 5GHz channels have erroneous (zero) center_freq value. Patch fixes problem and simplifies code a bit.

2011-01-28iwlwifi: do not set tx power when channel is changingStanislaw Gruszka4-8/+14
Mac80211 can request for tx power and channel change in one ->config call. If that happens, *_send_tx_power functions will try to setup tx power for old channel, what can be not correct because we already change the band.

2011-01-21cfg80211: Extend channel to frequency mapping for 802.11jBruno Randolf3-5/+8
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.

2011-01-19mac80211: track receiver's aggregation reorder buffer sizeJohannes Berg2-2/+4
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!

Looks that we do not set correctly antennas when scanning on 5Ghz band and when bluetooth is enabled, because priv->cfg->scan_tx_antennas[band] is only defined for IEEE80211_BAND_2GHZ.

2011-01-04iwlagn: enable only rfkill interrupt when device is downStanislaw Gruszka2-4/+11
Since commit 6cd0b1cb872b3bf9fc5de4536404206ab74bafdd "iwlagn: fix hw-rfkill while the interface is down", we enable interrupts when device is not ready to receive them. However hardware, when it is in some inconsistent state, can generate other than rfkill interrupts and crash the system. I can reproduce crash with "kernel BUG at drivers/net/wireless/iwlwifi/iwl-agn.c:1010!" message, when forcing firmware restarts. To fix only enable rfkill interrupt when down device and after probe. I checked patch on laptop with 5100 device, rfkill change is still passed to user space when device is down.
