Hi linux-bluetooth,
This series of patches add support for new advertisement monitor mgmt
opcodes by introducing new btmgmt commands into a new submenu
'monitor'. The new commands are ‘features’, ‘add’, and ‘remove’. They
provide the ability for users to query supported advertisement
monitoring features and add/remove monitor filters through btmgmt
console.
Changes in v3:
- Fix build errors
Changes in v2:
- Move features command into submenu and fix build warnings
- Move remove command into submenu and fix build warnings
- Move add command into submenu and fix build warnings
Michael Sun (3):
btmgmt: Add "monitor" btmgmt submenu and command "features"
btmgmt: Add command "remove" into "monitor" btmgmt submenu
btmgmt: Add command "add" into "monitor" btmgmt submenu

This patch introduces a new submenu "monitor" along with command
‘features’ to help user query for supported advertisement features. The
command will work with the new MGMT opcode
MGMT_OP_READ_ADV_MONITOR_FEATURES.
