            Bug ID: 248015
           Summary: Bluetooth HCI socket cannot send ACL messages
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: greg@unrelenting.technology

Trying to send ACL/L2CAP payloads over a raw HCI socket fails with errno 45, I
assume because of this check:

https://github.com/freebsd/freebsd/blob/c470df57b17914aedf532bebf57b4e6d6ba83b85/sys/netgraph/bluetooth/socket/ng_btsocket_hci_raw.c#L1609-L1612

What is the purpose of this check? I'm pretty sure on Linux, you can talk ACL
over a raw HCI socket..
