request packets with option37,38: replace the original option37,38 with its own;

discard the packets with option37,38; do not execute adding, discarding or

forwarding operation. Therefore, please check policy configuration of snooping

option37,38 on second device when obtaining the false address or no address is

obtained according to option37,38.
