I wrote the below code

    def na_reply_callback(req, reply_mac, iface):
        '\n                                Callback    that    reply    to    a    NS    with    a    NA\n                                '
        mac = req[Ether].src
        dst = req[IPv6].dst
        tgt = req[ICMPv6ND_NS].tgt
        rep = (Ether(src=reply_mac) / IPv6(src=tgt, dst=dst))
        rep /= ICMPv6ND_NA(tgt=tgt, S=0, R=0, O=1)
        rep /= ICMPv6NDOptDstLLAddr(lladdr=reply_mac)
        sendp(rep, iface=iface, verbose=0)
        print(('Reply    NA    for    target    address    %s    (received    from    %s)' % (tgt, mac)))
    _NDP_Attack_DAD_DoS(na_reply_callback, iface, mac_src_filter, tgt_filter, reply_mac)

What's a good function header?

Here's a good function header?
