2011-01-21cfg80211: Extend channel to frequency mapping for 802.11jBruno Randolf1-2/+3
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.

2011-01-21iwlagn: add support for waiting for notificationsJohannes Berg1-0/+46
In order to implement waiting for notifications, add a structure that captures the information, and a list of such structures that will be traversed when a command is received from the ucode. Use sparse checking to make sure calls to the prepare/wait/cancel functions are always nested correctly.

2011-01-04iwlagn: fix scan tx antenna setting on 5Ghz bandStanislaw Gruszka1-9/+5
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. To fix we check band before limiting antennas to first one. This allow to remove hard coded cfg->scan_tx_antennas[band].

2010-12-13iwlagn: implement layout-agnostic EEPROM readingJohannes Berg1-0/+6
The current EEPROM reading code has some layout assumptions that now turned out to be false with some newer versions of the EEPROM. Luckily, we can avoid all such assumptions by using data in the EEPROM itself, so implement using that. However, for risk mitigation purposes, keep the old reading code for current hardware for now.

There are two passive 2.4 GHz channels: 12 and 13. If you have a hidden SSID on those, you will not be able to connect to it because we don't send out probe requests there.
