I wrote the below code

    def ns_reply_callback(req, reply_mac, iface):
        '\n                                Callback    that    reply    to    a    NS    by    sending    a    similar    NS\n                                '
        mac = req[Ether].src
        dst = req[IPv6].dst
        tgt = req[ICMPv6ND_NS].tgt
        rep = ((Ether(src=reply_mac) / IPv6(src='::', dst=dst)) / ICMPv6ND_NS(tgt=tgt))
        sendp(rep, iface=iface, verbose=0)
        print(('Reply    NS    for    target    address    %s    (received    from    %s)' % (tgt, mac)))
    _NDP_Attack_DAD_DoS(ns_reply_callback, iface, mac_src_filter, tgt_filter, reply_mac)

What's a good function header?
 Here's a good function header?
