This patch fixes the opcodes of the Block/Unblock device commands to

This patch adds a missing confirm_name field to mgmt_ev_device_found.
Support for setting the correct value for this field is not implemented
yet, but having it part of the struct definition ensures that user-space
gets correct sized device_found events and is thereby able to do at
least rudimentary parsing of them.

We do not want the service cache to be enabled indefinitely after
mgmt_read_info is called. To solve this a timer is added which will
automatically disable the cache if mgmt_set_dev_class isn't called
within 5 seconds of calling mgmt_read_info.

Instead of having an explicit service cache command we can make the mgmt

This patch adds the dev_flags field to struct hci_dev. This new
flags variable should be used to define flags related to BR/EDR
and/or LE controller itself. It should be used to define flags
which represents states from the controller. The dev_flags is
cleared in case the controller sends a Reset Command Complete
Event to the host.
Also, this patch adds the HCI_LE_SCAN flag which was created to
track if the controller is performing LE scan or not. The flag
is set/cleared when the controller starts/stops scanning.
This is an initial effort to stop using hdev->flags to define
internal flags since it is exported to userspace by an ioctl.

The management protocol uses a single byte for error codes (aka command
status). In some places this value is directly copied from HCI and in
other a POSIX error number is used. This makes it impossible for
user-space to uniquily decipher the meaning of an error.
To solve this issue a new mgmt-specific set of error codes is added
along with a conversion table for HCI status values.

The kernel needs to know whether it should connect to a device over
BR/EDR or over LE. This is particularly important in the future when
dual-mode device may be connectable also over LE. It is also important

into user-space. Adding the type to the mgmt command also ensures
