The driver should not allow starting any type of scan on a stopped
P2P device. Current implementation only checked social scan.

The driver uses the bus_request platform operation to
request resources from the platform for a specific bandwidth.
Currently the driver requests resources for the maximum
theoretical bandwidth, when interface is brought up.
Refine this process a bit: now the driver will request a
small amount of resources when interface is up, and will only
issue the maximum request when connected.
This mechanism will be improved further in the future to make
more refined requests based on actual bandwidth.

Some dynamic debug printouts in driver are using print_hex_dump_bytes.
However, with dynamic debug disabled, print_hex_dump_bytes outputs to
log unconditionally.
Use print_hex_dump_debug instead to prevent log pollution when dynamic
debug disabled.

After setting HALP ICR bit, we keep it set until HALP unvote.
Masking HALP ICR should protect the driver from hitting the HALP ICR
over and over again. However, in case there is another MISC ICR
we will read the HALP ICR and issue a completion. This can lead to
a case where HALP voting is completed immediately, as the completion
is already set.
Reinit the HALP completion before the actual vote will clear previous
completions and protect from such cases.

In a fast disconnect/connect sequence, cfg80211_connect_result() can
fail to find the bss object which the driver is connecting to. Detailed
sequence of events:
* Driver is connected in STA mode
* Disconnect request arrives from user space. Driver disconnects and
calls cfg80211_disconnected() which adds new event to the
cfg80211_wq worker thread
* Connect request arrives from user space. cfg80211_connect() stores
ssid/ssid_len and calls rdev_connect()
* __cfg80211_disconnected() runs in worker thread and zero
wdev->ssid_len
* Connect succeeds. Driver calls cfg80211_connect_result() which fails
to find the bss because wdev->ssid_len is zero
To overcome this, upon connect request, store the bss object in the
driver and upon connect completion pass it to kernel using
cfg80211_connect_bss().

Upon connect timeout driver invokes _wil6210_disconnect() which iterates
over sta array and disconnects each connected sta. In practice, because
the connection is still ongoing and because cid is not yet allocated,
disconnect is not actually happening. This leaves FW in connecting
state while driver is in disconnected state.
To fix this, upon connect timeout, explicitly send WMI_DISCONNECT_CMDID
to FW to make sure it gets disconnected.

Driver always invoke cfg80211_disconnected() with locally_generated as
false.
Fix this by reporting true whenever the disconnect is triggered from
upper layers (cfg80211) or from within the driver itself (reset,
deinit).
