[PATCH v3 1/2] Bluetooth: hci_sync: Use address filtering when HCI_PA_SYNC is set

[PATCH v3 1/2] Bluetooth: hci_sync: Use address filtering when HCI_PA_SYNC is set

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

If HCI_PA_SYNC flag is set it means there is a Periodic Advertising
Synchronization pending, so this attempts to locate the address passed
to HCI_OP_LE_PA_CREATE_SYNC and program it in the accept list so only
reports with that address are processed.

[PATCH v3 2/2] Bluetooth: hci_sync: Use QoS to determine which PHY to scan

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This used the hci_conn QoS to determine which PHY to scan when creating
a PA Sync.
