mac80211: track needed RX chains for channel contexts
On each channel that the device is operating on, it may need to listen using one or more chains depending on the SMPS settings of the interfaces using it. The previous channel context changes completely removed this ability (before, it was available as the SMPS mode). Add per-context tracking of the required static and dynamic RX chains and notify the driver on changes. To achieve this, track the chains and SMPS mode used on each virtual interface and update the channel context whenever this changes. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
