Hi Maintainers, This patch series defines the new two-call MGMT interface for adding new advertising instances. Similarly to the hci advertising commands, a mgmt call to set parameters is expected to be first, followed by a mgmt call to set advertising data/scan response. The members of the parameters request are optional; the caller defines a "params" bitfield in the structure that indicates which parameters were intentionally set, and others are set to defaults. The main feature here is the introduction of min/max parameters and tx power that can be requested by the client. Min/max parameters will be used both with and without extended advertising support, and tx power will be used with extended advertising support. After a call for hci advertising parameters, a new TX_POWER_SELECTED event will be emitted to alert userspace to the actual chosen tx power. Additionally, to inform userspace of the controller LE Tx power capabilities for the client's benefit, this series also adds an MGMT command to query controller capabilities, which returns a flexible TLV format for future flexibility. All changes have been tested on hatch (extended advertising) and kukui (no extended advertising) chromebooks with manual testing verifying correctness of parameters/data in btmon traces, and our automated test suite of 25 single- and multi-advertising usage scenarios. A separate patch series will add support in bluetoothd. Thanks in advance for your feedback!
