 Scapy's command to reproduce the bug quickly:
 
 >> sendp(Ether(dst="ff:ff:ff:ff:ff:ff")/IP(src="0.0.0.0",dst="255.255.255.255")/UDP(sport=68,dport=67)/BOOTP(chaddr="00:30:48:xx:yy:zz")/DHCP(options=[("message-type","discover"),"end"]),
 >>  iface="wm0")
 
 Do above command more than 47 times.
 
 I can't understand why it occurs. Please debug!
