From: Luca Coelho <[email protected]>
Hi,
Here's the thjird set of patches intended for v5.14. It's the usual
development, new features, cleanups and bugfixes.
The changes are:
* Some fixes in IML (image loader) DMA handling;
* Fixes in WoWLAN;
* Some other small fixes, clean-ups and improvements.
As usual, I'm pushing this to a pending branch, for kbuild bot, and
will send a pull-request later.
Please review.
Cheers,
Luca.

From: Naftali Goldstein <[email protected]>
When operating in AP mode with NICs supporting the AP_LINK_PS hw flag,
mac80211 doesn't need to start/stop queueing tx for connected stations
because the FW already handles that.

In the case of gen3 devices with image loader (IML) support,
we were leaking the IML DMA allocation and never freeing it.
Fix that.

From: Emmanuel Grumbach <[email protected]>
It's been a while that the firmware uses LONG_GROUP by default
and not LEGACY_GROUP.
Until now the firmware wrongly advertise the WOWLAN_GET_STATUS
command's version with LEGACY_GROUP, but it is now being fixed.
In order to support both firmwares, first try to get the version
number of the command with the LONG_GROUP and if the firmware
didn't advertise the command version with LONG_GROUP, try to get
the command version with LEGACY_GROUP.

We don't fill in phy_data.d1 in no-data RX, and thus we
pretend some data is actually filled in radiotap when it
isn't or has default (zero) values.
Fill in phy_data.d1 appropriately, and while at it also
move the info_type initialization into the initializer.

In gen3, after firmware is alive, we no longer need the
firmware and image loader images, only the context info
itself and PRPH info/scratch need to remain.
Call iwl_pcie_ctxt_info_gen3_free() appropriately in the
alive callback (iwl_trans_pcie_gen2_fw_alive()) with a new
argument indicating whether it can free everything or only
partially.
The context info and PRPH scratch are also not needed after
PNVM load, but we don't have a good hook for freeing after
that, so keep them for now.

After firmware alive, iwl_trans_pcie_gen2_fw_alive() is called
to free the context info. However, on gen3 that will then free
the context info with the wrong size.
Since we free this allocation later, let it stick around until
the device is stopped for now, freeing some of it earlier is a
separate change.

In case of unbinding, the FW would remove the session protection time
events without sending a notification, so explicitly cancel the
session protection, so future requests for mgd_prepare_tx() would not
assume that the session protection is running.

2.32.0
From: Naftali Goldstein <[email protected]>
These two version updates deprecate the need to set/get the nonqos sequence
counter during suspend/resume flow respectively; NICs supporting this
version maintain this counter internally and don't lose it during the
suspend/resume flow.
Note that this means that for such NICs the NON_QOS_TX_COUNTER_CMD is no
longer ever sent.
