In AP mode, don't attempt to program GTKs into the
device, they're used for TX only so not needed and
programming them causes error messages. Also, in
this case and if key programming fails, avoid trying
to remove the key that isn't present later.

This allows to test fw restart flow. The hook in transport

to the op_mode allows to use the fw API to actually send a

When BT traffic load gets higher, we want to avoid using the

When modifying a MAC, we update its beacon system time which
is taken as a base to calculate TBTT. The firmware doesn't use
the new timestamp because the time is never used after the MAC
and broadcast station were added, but it is safer to not rely
on this and avoids the overhead of reading the register every
time the MAC is updated.

Newer devices can work on different buses. This means that
their configuration can be shared between different buses.
Hence the configuration structures should exported to all
the buses and not only to PCIE. Change this.
Note that this requires all the fields to be the same
amongst the buses. If differences will appear, we can always
define a part that is bus dependent. Today, this is not
needed.

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.

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.

There's a bug that causes the rate scaling to get stuck
when it has to use single-stream rates with a peer that
can do GF and SGI; the two are incompatible so we can't
use them together, but that causes the algorithm to not
work at all, it always rejects updates.
Disable greenfield for now to prevent that problem. The
MVM driver currently only works on devices that don't
support greenfield anyway, but better be safe and not
allow us to forget about this.

When we stop an AGG session, we need to look at the sequence
numbers in in the private area of the ieee80211_sta struct.
This allows us to know is the queue is empty. To get access
to this private area, we use fw_id_to_mac_id that maps
sta_id (index of the STA in fw table) to ieee80211_sta.
When the STA exists in fw, but not in mac80211, we set
an ERR ptr in fw_id_to_mac_id.
But if we first set an ERR ptr to fw_id_to_mac_id, and only
then flush the queues, then we won't be able to access the
sequence numbers in ieee80211_sta from the reclaim flow.
This means that we will never be able to release an AGG
queue when a station is deleted.
So first, flush the queue. That will let the reclaim flow
call iwl_mvm_check_ratid_empty which will disable the AGG
queue as needed, and only then, remove the mapping in
fw_id_to_mac_id.

This flow happens when we get a failed single Tx response
on an AMPDU queue. In this case, the frame won't be sent
any more. So we need to move the window on the recipient
side. This is done by a BAR.
Now if we are in the following case: 10, 12 and 13 are ACKed
and 11 isn't.
10 11 12 13.
V X V V
Then, 11 will be sent 16 times as an MPDU (as oppsed to
A-MPDU). If this failed, we are entering the flow described
above. So we need to send a BAR with ssn = 12.
But in this case, the scheduler will tell us to free frames
up to 13 (included).
So, it is perfectly possible to get a failed single Tx
response on an AMPDU queue that makes the scheduler's ssn
jump by more than 1 single packet.
