The assignment line was deleted by mistake:
rtap = skb_push(skb, rtap_len);
I'll fix that.

Some of wil6210 configuration variables are platform specific.
Add platform op to allow the platform driver to change the wil6210
default configuration.

Add support for Access Category to select queue for transmit packets.
The callback wil_select_queue will return the queue id [0..3] to use for
the current skb transmission.
This feature is disabled by default. Use ac_queues module param to enable.

From: Ahmad Masri <amasri@codeaurora.org>
Until now all stations (notably in AP mode) would share the same
queue/s exposed via netdev. This meant that whenever a single
station's ring became full all queues got stopped.
With the queues per station feature each station will have its own
net queue/s and it will not block other stations' transmission in
case its vring is full.
Driver will add queue/s per station when creating a new netdev.
The mapping between a station and its queues will be by sta cid.
Once a new sta connects the driver will open its queues
(can be one or four AC queues) for transmit. The driver uses the
same logic of ring capacity usage to wake the net queues.
Last four netdev queues are used for unclassified traffic
(e.g. when there's no cid for given DA) which is mostly multicast.
This feature is controlled by a q_per_sta module param
which is disabled by default.

To: Kalle Valo; +Cc: Dedy Lansky, linux-wireless, wil6210, Maya Erez
From: Dedy Lansky <dlansky@codeaurora.org>
In AP mode with multiple clients, driver stops net queue
(netif_tx_stop_queue) upon first ring (serving specific client)
becoming full. This can have negative effect on transmission to
other clients which may still have room in their corresponding rings.
Implement new policy in which stop/wake net queue are not used. In
case there is no room in the ring for a transmitted packet, drop the
packet.
New policy is disabled by default and can be enabled with new
drop_if_ring_full module param.

From: Maya Erez @ 2019-01-28 15:36 UTC (permalink / raw)
To: Kalle Valo; +Cc: Ahmad Masri, linux-wireless, wil6210, Maya Erez
From: Ahmad Masri <amasri@codeaurora.org>
New FW added support for upto 20 clients in AP mode. Change the driver
to support this as well. FW reports it's max supported associations in
WMI_READY_EVENT. Some WMI commands/events use cidxtid field which is
limited to 16 cids. Use new cid/tid fields instead.
For Rx packets cid from rx descriptor is limited to 3 bits (0..7),
to find the real cid, compare transmitter address with the stored
stations mac address in the driver sta array.
EDMA FW still supports 8 stations. Extending the support to 20
stations will come later.

From: Dedy Lansky <dlansky@codeaurora.org>
Upon status ring handling, in case there are both unicast and
multicast (cid == max) status messages to handle, wrong sta statistics
might get updated.
Fix this by setting stats to NULL upon invalid cid
(e.g. == max_assoc_sta).

HALP ICR is set as long as the FW should stay awake.
To prevent its multiple handling the driver masks this IRQ bit.
However, if there is a different MISC ICR before the driver clears
this bit, there is a risk of race condition between HALP mask and
unmask. This race leads to HALP timeout, in case it is mistakenly
masked.
Add a flag to indicate if HALP ICR should be handled.

Add explicit check for null and make sure ies1/ies2 are not accessed in
such a case.
spos might be null and be accessed inside _wil_cfg80211_merge_extra_ies.
Add explicit check for null in the while condition statement and make
sure spos is not accessed in such a case.

To: Kalle Valo; +Cc: Ahmad Masri, linux-wireless, wil6210, Maya Erez
From: Ahmad Masri <amasri@codeaurora.org>
Accessing some of the memory of the device while the device is
resetting or suspending may cause unexpected error as the HW is still
not in a stable state. Prevent this access to guarantee successful
read/write memory operations.
