From: Ilia Kolomisnky <iliak@xxxxxx> This param allows role switch request while accepting a new acl connection. This is an enhancement to l2cap L2CAP_LM role switching capability which allows requesting role switch without modification to the application code. It was observed that operating as a master of piconet (as oposed to scatternet config) is beneficial when qos (flow_spec) guarantees are requested.
