This patch moves the sysfs device used by the netdev from the device of
the first connected peer to the hci sysfs device. Using the sysfs device
of hci instead of the first connected device fixes this issue such that
the sysfs group of tx-0 and bt0 kobject are still present after the last
peer has been deleted and all sysfs entries can be removed.

This patch fixes an issue with the netdev not being unregistered when
the last peer is deleted. Removing the logical negation operator on the
boolean solves this issue. If the last peer is removed the condition
will be true, and the delete_netdev() is scheduled.

This patch moves the hardware setting before calling the driver start
callback which activates the receive handling. The hardware setup
contains settings like address filtering which should be setup before
activate the receive handling on the transceiver. These setting are
protected by ieee802154_check_concurrent_iface check. This means we
need to set these registers once before calling drv_start and can't
be overwritten by other interfaces.

This patch adds the routine to apply the DDC parameter from device
specific ddc file.
Once the device is rest to operational mode, optionally, it can
download the device specific configration (DDC) parameters before
the BlueZ starts the stack initialization.
It opens the DDC file based on HW_VARIANT and DEV_REVISION and
send ID/Value with HCI_Intel_Write_DDC command.
Format of DDC file
DDC file contains one or more number of DDC structure.
DDC Structure
It has 'Length' field of one octet, DDC 'ID' field of
two octets followed by the array of DDC 'Value' that gives
the value of parameters itself.
'Length' contains the length of DDC 'ID' and DDC 'Value'.
+------------+----------+
| Size(byte) | Name |
+------------+----------+
| 1 | Length |

This patch fixes the command length alignment issue for Intel Bluetooth
8260.
The length of parameters in the firmware downloading command must be
multiplication of 4. If not, the command must append Intel_NOP command
with extra parameters, zeros, at the end, and the firmware file is
already included Intel_NOP command for alignment.
This patch checks the next command and if the next command is Intel_NOP
command, it reads the Intel_NOP command and send them together.
For example, if the data from the firmware file looks like this:
8E FC 03 11 22 33 02 FC 03 00 00 00
Previously, btusb sends two commands:
09 FC 06 8E FC 03 11 22 33
09 FC 06 02 FC 03 00 00 00
This won't work because the length of parameters are 6 which violates
the 4 byte alignment.
This patch will append them together and send as one command:
09 FC 0C 8E FC 03 11 22 33 02 FC 03 00 00 00

The encryption key size for LTKs is supposed to be applied only at the
moment of encryption. When generating a Link Key (using LE SC) from
the LTK the full non-shortened value should be used. This patch

the key size when passing the value to HCI.

During the initial setup stage of a controller, the low-level transport
is actually active. This means that HCI_UP is true. To avoid toggling
the transport off and back on again for normal operation the kernel
holds a grace period with HCI_AUTO_OFF that will turn the low-level
transport off in case no user is present.
The idea of the grace period is important to avoid having to initialize
all of the controller twice. So legacy ioctl and the new management
interface knows how to clear this grace period and then start normal
operation.
For the user channel operation this grace period has not been taken into
account which results in the problem that HCI_UP and HCI_AUTO_OFF are
set and the kernel will return EBUSY. However from a system point of
view the controller is ready to be grabbed by either the ioctl, the
management interface or the user channel.
This patch brings the user channel to the same level as the other two
entries for operating a controller.
