Johannes Berg 3c15a0fb61 Revert "iwlwifi: mvm: remove P2P_DEVICE support"
This reverts commit eebfc9394e.

This wasn't intended to be included here, my mistake. I
accidentally merged a mac80211 fixes tree here that had
this change, when it wasn't even intended to be there.

Johannes Berg eebfc9394e iwlwifi: mvm: remove P2P_DEVICE support
Unfortunately, advertising P2P_DEVICE support was a little
premature, a number of issues came up in testing and have
been fixed for 3.10. Rather than try to backport all the
different fixes, disable P2P_DEVICE support in the drivers
using it. For iwlmvm that implies disabling P2P completely
as it can't support P2P operation w/o P2P Device.

Emmanuel Grumbach 881acd8987 iwlwifi: mvm: clean up invalid station handling
Using IWL_MVM_STATION_COUNT and IWL_INVALID_STATION together
isn't a good idea as they have different values. Always use
IWL_MVM_STATION_COUNT for an invalid station in MVM and move
the definition of the IWL_INVALID_STATION constant into the
DVM driver to avoid making such mistakes again. The one use
in the transport code can be hard-coded to -1 instead as the
station ID is passed as an integer there.

Alexander Bondar 5ee2b2154e iwlwifi: mvm: don't disable power management due to P2P device
Currently power management is supported only when only a single
virtual interface is present. The driver verifies number of created
interfaces and disables power management when multiple interfaces
present. However, this rule does not extend to a P2P device that is
handled differently in the firmware. If a P2P device is added power
management can remain enabled.

Johannes Berg f0c2646af4 iwlwifi: mvm: implement remote wake
With remote wake, the firmware creates a TCP connection
and sends some configurable data on it, until a special
TCP data packet from the server is received that triggers
a wakeup. The configuration is a bit tricky because it is
based on packet pattern matching but this is hidden in
the driver and the exposed API in cfg80211 is just based
on the required TCP connection parameters.

Emmanuel Grumbach e3d9e7ce4c iwlwifi: mvm: support IEEE80211_AMPDU_TX_STOP_FLUSH
mac80211 tells us when we need to dump the frames from the
AGG queue instead of releasing them as single MPDUs.
Being able to differentiate between the different cases
(IEEE80211_AMPDU_TX_STOP_*) allows us to handle races better.

When the station is removed, mac80211 asks to flush and
removes the station right away.
This allows to avoid a case where we still have frames in
AGG queues, but the station has been remove already.

Note that we can have frames on the shared queues, but this
is not a problem: the station in the fw will be kept until
all the frames on the shared queues have been drained.
AGG queues are a special case since they are dynamically
allocated.

Johannes Berg 38a12b5b02 iwlwifi: mvm: fix AP/GO mode station removal
When stations are removed while packets are in the queue,
we drain the queues first, and then remove the stations.
If this happens in AP mode while the interface is removed
the MAC context might be removed from the firmware before
we removed the station(s), resulting in a SYSASSERT 3421.
This is because we remove the MAC context from the FW in
stop_ap(), but only flush the station drain work later in
remove_interface().

Refactor the code a bit to have a common MAC context
removal preparation first to solve this.

Johannes Berg 7a4539736e iwlwifi: mvm: update station when marked associated
In managed mode, the HT/VHT capabilities aren't set when
the station is initially added, so update the station
when it is marked associated. In AP/GO mode, the station
will typically be added with full capabilities today,
but an upcoming change in hostapd may mean a similar
scenario as for managed mode, therefore do the update
unconditionally.

Johannes Berg 210a544e78 iwlwifi: mvm: don't delay the association until after beacon

still start the association process and set the MAC in
the firmware to associated only after having received a
beacon with DTIM period by reacting to the new change
flag (BSS_CHANGED_DTIM_PERIOD) from mac80211.

This reduces the association time in these cases.
