 Bitmask values for notifying/requesting notification of the state of a physical link.

 These values have a two fold purpose:

 1) They can be used along with TBTPhysicalLinkStateNotifierCombinations to specify

 a set of baseband change events for which notification is desired.

 2) They can be used to notify the state of a physical link or a subset of that state.

 For example if only mode change events are being monitored, then at each mode change event

 only the bit reperesenting the new mode will be returned, however if the whole link state

 is required, then a combination of bit values indicating that state will be returned.

 THESE BIT VALUES MUST ONLY BE USED WHEN REQUESTING NOTIFICATION, OR WHEN PARSING THE

 RESULTS OF A NOTIFICATION. All other baseband state activities should use one of the 

 appropriate Bluetooth SIG specified enums

 API class for setting up an L2Cap channel configuration.

 This class may be used to set all or a subset of the following configuration

 items:

 Channel Reliability (and associated timer)

 Maximum Transmission Unit (MTU) value preferred during MTU negotiation

 Maximum Receive Unit (MRU) value preferred during MRU negotiation

 Minimum MTU value acceptable during MTU negotiation

 Minimum MRU value acceptable during MRU negotiation

 Channel Priority

 If a configuration item is to be set, then its 'Set' or 'Configure'

 method should be called.

 Once a TL2CapConfig object has been set up it can be used to configure a socket

 using RSocket::SetOption or RSocket::Ioctl (or the CBluetoothSocket equivalents).

 If the preferred Maximum Transmission Unit (MTU) value is specified but its

 minimum acceptable value is not specified in the same object, then the minimum

 acceptable value will be implicitly taken to be equal to the preferred MTU by

 the L2CAP APIs processing the object. This means that only an MTU greater than or

 equal to the preferred MTU will be accepted from the peer during negotiation.

 If the Maximum Receive Unit (MRU) value is specified but its minimum acceptable

 value is not, then the minimum acceptable value is implicitly taken to be equal

 to the protocol minimum (48 bytes) by the L2CAP APIs processing the object.

 Note that even though this API allows setting of Obsolescence timer, outgoing

 packet flushing may not be supported on all hardware.
