2011-02-08iwlagn: Re-enable RF_KILL interrupt when downDon Fry1-0/+6
With commit 554d1d027b19265c4aa3f718b3126d2b86e09a08 only one RF_KILL interrupt will be seen by the driver when the interface is down. Re-enable the interrupt when it occurs to see all transitions.

2011-02-01iwlwifi: fix beacon notification parsingJohannes Berg1-8/+8
The beacon notification changed between 4965 and agn because the embedded TX response changed, but iwlwifi was never updated to know about this.

2011-02-01iwlwifi: support RSN IBSSJohannes Berg1-1/+10
In order to support RSN IBSS, we need to (ok actually maybe it's just easiest to) disable group key programming so that any group-addressed frames will be decrypted in software which handles the per-station keys for this easily. We could keep the encryption in the device, but that takes more work and seems unnecessary. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>

If PAN functionality is present, advertise P2P interface type support and thus support for P2P.

2011-01-19mac80211: track receiver's aggregation reorder buffer sizeJohannes Berg1-1/+2
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!

2011-01-04iwlagn: enable only rfkill interrupt when device is downStanislaw Gruszka1-4/+5
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.

2010-11-15iwlagn: new RXON processing for modern devicesJohannes Berg1-338/+47
In order to simplify the flow, and make new enhancements easier, separate out the RXON processing for modern AGN (5000 and newer) from RXON processing for the older 3945 and 4965 devices. Avoid changing these old ones to avoid regressions and move their code to a new file (iwl-legacy.c). 4965 gets the commit_rxon that used to be common for all AGN devices, but with removed PAN support. The new RXON processing is more central and does more work in committing, so that it is easier to follow. To make it more evident what is split out for legacy, split the necessary operations for that into a new struct iwl_legacy_ops. Those parts that still exist in the new AGN code don't need to be parametrized.

Almost anywhere in the code we avoid committing rxon while performing scan, and make rxon commit when scan complete. However in some places in the code we do not follow that rule. This patch fix that problem in iwlagn_configure_filter().

2010-10-08iwlagn: fix default calibration table sizeShanyu Zhao1-1/+1
iwlagn driver uses the IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE as the chain noise reset calibration index and IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE+1 as the chain noise gain calibration index, if not specified by the TLV value in the new firmware format. However, this is broken if we need to add more calibrations like the temperature offset calibration because we increased IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE by 1. To fix this issue, define IWL_DEFAULT_STANDARD_PHY_CALIBRATE_TBL_SIZE and use it as the calibration index instead. We still keep the IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE as a sanity check for the TLV value given by ucode.
