The PCIE Workaround register (AR_WA/0x4004) is used to handle
various hardware quirks. For AR9002 chips, AR_WA_D3_L1_DISABLE
is used to prevent the HW from automatically entering L1 state
when D3 is enforced.
AR_WA_D3_L1_DISABLE has to be enabled for a few AR9280 based
cards, mark them based on their PCI subdevice/subvendor IDs
and enforce it in ar9002_hw_configpcipowersave().

We have usb_deregister() call in our rmmod routine. deauth,
shutdown etc. commands will be sent to FW later when bus
driver calls disconnect handler.
This mechanism works fine with SDIO and PCIe interfaces, but
there is an issue with USB.
USB bus driver returns all URBs submitted for receiving data
and command response immediately after usb_deregister() with
failure status. Hence we don't send deauth, shutdown etc.
command to firmware.
The problem is fixed by moving code from disconnect handler to
rmmod routine for USB interface.

Bug 60747 - 1286:2044 [Microsoft Surface Pro]
Marvell 88W8797 wifi show 3 interface under network
https://bugzilla.kernel.org/show_bug.cgi?id=60747
This issue was also reported previously by OLPC and some folks from
the community.
There are 3 network interfaces with different types being created
when mwifiex driver is loaded:
1. mlan0 (infra. STA)
2. uap0 (AP)
3. p2p0 (P2P_CLIENT)
The Network Manager attempts to use all 3 interfaces above without
filtering the managed interface type. As the result, 3 identical
interfaces are displayed under network manager. If user happens to
click on an entry under which its interface is uap0 or p2p0, the
association will fail.
Work around it by removing the creation of AP and P2P interfaces
at driver loading time. These interfaces can be added with 'iw' or
other applications manually when they are needed.

When initiating a transparent eSCO connection, make use of T2 settings

When CVSD is requested and eSCO is supported, try to establish eSCO

S1, D1, D0 settings.
To know which setting should be used, conn->attempt is used. It

as the index for the fallback settings table.
These setting and the fallback order are described in Bluetooth HFP 1.6

Older Bluetooth devices may not support Setup Synchronous Connection or
SCO transparent data. This is indicated by the corresponding LMP feature
bits. It is not possible to know if the adapter support these features
before setting BT_VOICE option since the socket is not bound to an
adapter. An adapter can also be added after the socket is created. The
socket can be bound to an address before adapter is plugged in.
Thus, on a such adapters, if user request BT_VOICE_TRANSPARENT, outgoing
connections fail on connect() and returns -EOPNOTSUPP. Incoming
connections do not fail. However, they should only be allowed depending
on what was specified in Write_Voice_Settings command.
EOPNOTSUPP is choosen because connect() system call is failing after
