Add _MCDI_DWORD() which yields an lvalue for the given dword field
and change MCDI_DWORD(), MCDI_SET_DWORD() and MCDI_QWORD() to use it.
Fold the rather trivial MCDI_PTR2() into MCDI_PTR() and _MCDI_DWORD().
Remove MCDI_SET_DWORD2() and MCDI_QWORD2(). MCDI_DWORD2() should also
go, but it still has one user which we'll get rid of later.

When initiating a transparent eSCO connection, make use of T2 settings
at first try. T2 is the recommended settings from HFP 1.6 WideBand
Speech. Upon connection failure, try T1 settings.
When CVSD is requested and eSCO is supported, try to establish eSCO
connection using S3 settings. If it fails, fallback in sequence to S2,
S1, D1, D0 settings.
To know which setting should be used, conn->attempt is used. It
indicates the currently ongoing SCO connection attempt and can be used
as the index for the fallback settings table.
These setting and the fallback order are described in Bluetooth HFP 1.6
specification p. 101.

Synchronous Connection Complete event can return error "Connection
Rejected due to Limited resources (0x10)".
Handling this error is required for SCO connection fallback. This error
happens when the server tried to accept the connection but failed to
negotiate settings.
This error code has been verified experimentally by sending a T2 request
to a T1 only SCO listener.

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
selecting route but before any connection attempt.

The tty_port can be released in two cases: when we get a HUP in the
functions rfcomm_tty_hangup() and rfcomm_dev_state_change(). Or when the
user releases the device in rfcomm_release_dev().
In these cases we set the flag RFCOMM_TTY_RELEASED so that no other
function can get a reference to the tty_port.
The use of !test_and_set_bit(RFCOMM_TTY_RELEASED) ensures that the
'initial' tty_port reference is only dropped once.
The rfcomm_dev_del function is removed becase it isn't used anymore.

In case of a Low Energy only controller it makes no sense to configure
the full BR/EDR event mask. It will just enable events that can not be

this value.
Use event mask 0x90 0xe8 0x04 0x02 0x00 0x80 0x00 0x20 for LE-only
controllers which enables the following events:
Disconnection Complete
Encryption Change

When a socket is in deferred state there does actually exist an
underlying connection even though the connection state is not yet
BT_CONNECTED. In the deferred state it should therefore be allowed to
get socket options that usually depend on a connection, such as
SCO_OPTIONS and SCO_CONNINFO.
This patch fixes the behavior of some user space code that behaves as
follows without it:
$ sudo tools/btiotest -i 00:1B:DC:xx:xx:xx -d -s
accept=2 reject=-1 discon=-1 defer=1 sec=0 update_sec=0 prio=0 voice=0x0000
Listening for SCO connections
bt_io_get(OPT_DEST): getsockopt(SCO_OPTIONS): Transport endpoint is not connected (107)
Accepting connection
Successfully connected to 60:D8:19:xx:xx:xx. handle=43, class=000000
The conditions that the patch updates the if-statements to is taken from
similar code in l2cap_sock.c which correctly handles the deferred state.

When an Xin6 tunnel is set up, we check other netdevices to inherit the link-
local address. If none is available, the interface will not have any link-local
address. RFC4862 expects that each interface has a link local address.
Now than this kind of tunnels supports x-netns, it's easy to fall in this case
(by creating the tunnel in a netns where ethernet interfaces stand and then
moving it to a other netns where no ethernet interface is available).
RFC4291, Appendix A suggests two methods: the first is the one currently
implemented, the second is to generate a unique identifier, so that we can
always generate the link-local address. Let's use eth_random_addr() to generate
this interface indentifier.
I remove completly the previous method, hence for the whole life of the
interface, the link-local address remains the same (previously, it depends on
which ethernet interfaces were up when the tunnel interface was set up).
