| * | iwlwifi: introduce beacon contextJohannes Berg2010-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | Only one context can be beaconing at a time, but we need to track which one. Introduce a new variable priv->beacon_ctx to do that. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of HT configuration semantically belongs into the context, even if right now it will never be different between contexts.

| * | iwlwifi: add context pointer to stationJohannes Berg2010-08-27

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the default context is initialised to zero, and the default flags are zero, no more code is needed to initialise them right now, but another context can have different default flags.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When bluetooth indicated high load, we should use only antenna A in 2.4 GHz for management frames.

Additionally, disable reacting to the BT profile notification when in IBSS mode, it likely won't be sent by the device to start with though. Also, in IBSS mode, BT coexistence isn't as fully-featured and we must use a single antenna only. So instead of peppering the code with new checks, simply pretend we are in high BT traffic load, which has the needed effect of disabling antenna B use.

Add controls to improve the situation by making rate scaling depend on the BT load. When there's high bluetooth traffic load, there's little point in trying to aggregate as BT traffic would disrupt the aggregated frames all the time, so simply don't start sessions then. When BT traffic returns to lower levels, the rate scaling will come here again automatically when wifi traffic is high enough, and then it will be able to successfully enable aggregation.
