Subject: [PATCH 20/20] staging: wfx: update TODO

From: Jérôme Pouiller <jerome.pouiller@...abs.com>

Update the TODO list associated to the wfx driver with the last
progresses and last remarks made by reviewers.

The items about support for P2P and mesh have also been removed. Indeed,
it seems that the device does not fully support them.

 This is a list of things that need to be done to get this driver out of the
 staging directory.
 
-  - All structures defined in hif_api_*.h are intended to sent/received to/from
-    hardware. All their members whould be declared __le32 or __le16.
-    See:
+  - The HIF API is not yet clean enough.
+
+  - Fix support for big endian architectures. See:
        https://lore.kernel.org/lkml/20191111202852.GX26530@ZenIV.linux.org.uk
 
-  - Once previous item done, it will be possible to audit the driver with
-    `sparse'. It will probably find tons of problems with big endian
-    architectures.
+  - The pointers returned by allocation functions are always checked.
 
-  - hif_api_*.h whave been imported from firmware code. Some of the structures
-    are never used in driver.
+  - The code that check the corectness of received message (in rx_helper()) can
+    be improved. See:
+       https://lore.kernel.org/driverdev-devel/2302785.6C7ODC2LYm@pc-42/
 
-  - Driver try to maintains power save status of the stations. However, this
-    work is already done by mac80211. sta_asleep_mask and pspoll_mask should be
-    dropped.
-
-  - wfx_tx_queues_get() should be reworked. It currently try compute itself the
-    QoS policy. However, firmware already do the job. Firmware would prefer to
-    have a few packets in each queue and be able to choose itself which queue to
-    use.
+  - Support for SDIO with external IRQ is broken.
 
   - As suggested by Felix, rate control could be improved following this idea:

   - When driver is about to loose BSS, it forge its own Null Func request (see

   - Feature called "secure link" should be either developed (using kernel

     So, fix it (by replacing the mutex with a semaphore) or drop it.
