    [Bluetooth] Track connection packet type changes · a8746417

    The connection packet type can be changed after the connection has been
    established and thus needs to be properly tracked to ensure that the
    host stack has always correct and valid information about it.
    
    On incoming connections the Bluetooth core switches the supported packet
    types to the configured list for this controller. However the usefulness
    of this feature has been questioned a lot. The general consent is that
    every Bluetooth host stack should enable as many packet types as the
    hardware actually supports and leave the decision to the link manager
    software running on the Bluetooth chip.
    
    When running on Bluetooth 2.0 or later hardware, don't change the packet
    type for incoming connections anymore. This hardware likely supports
    Enhanced Data Rate and thus leave it completely up to the link manager
    to pick the best packet type.
