[BlueZ,v4,3/3] adapter: set quality report feature

Commit Message

Joseph Hwang June 28, 2021, 10 a.m. UTC

This patch adds the function to enable/disable the quality report
experimental feature in the controller through MGMT_OP_SET_EXP_FEATURE.

A user space process can enable/disable the quality report feature
by sending a property changed signal to the bluetoothd. The bluetoothd
can set up the signal handlers to handle the signal in a file under
plugins/ to call this function.

Note that the bluetoothd calls the experimental feature only when
the quality_report_supported flag is true.
