The driver reporting IEEE80211_TX_STAT_ACK is not being handled
correctly. The driver should only report on TSR_TMO flag is not
set indicating no transmission errors and when not IEEE80211_TX_CTL_NO_ACK
is being requested.

It appears that the drivers does not go into power save correctly the
NULL data packets are not being transmitted because it not enabled
in mac80211.
The driver needs to capture ieee80211_is_nullfunc headers and
copy the duration_id to it's own duration data header.

It appears that the driver still transmits in CTS protect mode even
though it is not enabled in mac80211.
That is both packet types PK_TYPE_11GA and PK_TYPE_11GB both use CTS protect.
The only difference between them GA does not use B rates.
Find if only B rate in GB or GA in protect mode otherwise transmit packets
as PK_TYPE_11A.

-std=gnu89 is specified by the top Makefile. Adding it in a driver
Makefile is redundant.
A driver should avoid specifying the optimization flag.

Currently calls to wfx_alloc_hif are not checking for a null return
when a memory allocation fails and this leads to null pointer
dereferencing issues. Fix this by adding null pointer checks and
returning passing down -ENOMEM errors where necessary. The error
checking in the current driver is a bit sparse, so this may need
some extra attention later if required.

Original code allows to detect an unjoin request during a scan and
delaying the unjoin request. However, it is far easier to just block the
unjoin request until the end of the scan request.
In fact, it is already the case since scan and unjoin are protected by
conf_mutex. So, currently, the handling of delayed_unjoin is just dead
code.

mac80211 specification does not forbid hw_scan() to call
ieee80211_scan_completed(). However, from userspace point of view, not
all applications support this behavior. In particular, the code of iw
contains a big fat warning:
/*
* This code has a bug, which requires creating a separate
* nl80211 socket to fix:
* It is possible for a NL80211_CMD_NEW_SCAN_RESULTS or
* NL80211_CMD_SCAN_ABORTED message to be sent by the kernel
* before (!) we listen to it, because we only start listening
* after we send our scan request.
[...]
* Alas, the kernel doesn't do that (yet).
*/
So, we have to avoid to call ieee80211_scan_completed() from hw_scan()
(it's a kind of unwritten rule).
This patch relocates the hw_scan() process to a work_struct to fix the
problem.

Scan requests from mac80211 must be splitted in a few hardware requests
(it is necessary to split channels with active scan and channels with
passive scan). Current code schedules a work_struct for each hardware
request and one delayed_work to handle scan timeout.
It is far simpler to run send all the hardware requests synchronously
and replace delayed_work with a simple wait_for_completion_timeout().

If scan fails, status is returned in hif_ind_scan_cmpl. hif_scan
always return a success. So, we can simplify the code.

The struct hif_req_edca_queue_params comes from hardware API. It is not
intended to be manipulated in upper layers of the driver.
So, this patch:
1. relocate the handling of this struct in hif_set_edca_queue_params()
(the low level function)
2. replace it in wfx_vif by the mac80211 equivalent: struct
ieee80211_tx_queue_params

mac80211 already call wfx_conf_tx() on every VIF instanciation. So, the
driver does not need to do it.
Note that current code did dirty things with wvif->edca_params. This
struct was initialized, but only 'queue_id' was really used. The other
members are only used to store temporary values.

Intermediate structure wfx_edca_params does not help. This patch

It is useless to keep uapsd_info in struct wfx_vif. This structure can
be rebuilt just before to be sent.
In add, the struct hif_mib_set_uapsd_information comes from hardware
API. It is not intended to be manipulated in upper layers of the driver.
So, this patch relocates the handling of this struct to
hif_set_uapsd_info() (the low level function).

Current code try to not exchange data with device if it is not
necessary. However, it seems that the additional code does not provide
any gain. So, we prefer to keep a simpler code.

Power save status is already available in bss_conf. So there is no
reason to keep information duplicated in wvif->powersave_mode.
In add, type of wvif->powersave_mode is low level struct made to
communicate with device. We would like to limit usage of this kind of
struct in upper layers of the driver.

When user try to launch scan while connected, it is necessary to notify
the AP that we cannot receive data (using power save mode).
Firmware already handles this automatically so the code in the driver is
redundant and can be dropped.
By edge effect, hack of scan status in wfx_set_pm() is now useless.

In the old days, wfx_do_join() could be called from different contexts.
Now that wfx_do_join() is called only from one place, it is cleaner to
keep lock and unlock of data inside the function.
