    ieee802154/nl-mac.c: make some MLME operations optional · 56aa091d
    Werner Almesberger authored
    Check for NULL before calling the following operations from "struct
    ieee802154_mlme_ops": assoc_req, assoc_resp, disassoc_req, start_req,
    and scan_req.
    
    This fixes a current oops where those functions are called but not
    implemented. It also updates the documentation to clarify that they
    are now optional by design. If a call to an unimplemented function
    is attempted, the kernel returns EOPNOTSUPP via netlink.
    
    The following operations are still required: get_phy, get_pan_id,
    get_short_addr, and get_dsn.
    
    Note that the places where this patch changes the initialization
    of "ret" should not affect the rest of the code since "ret" was
    always set (again) before returning its value.
