Hi, Recently I find a wpan-ping problem: wpan-ping process is always running, when there is another process runing on wpan interface, which will also transmit packets via wpan, the non-wpanping packets will also be received by recv() of wpan-ping, leading to the "Sequence number did not match" problem. It seems that the recv() function can not filter out non-wpanping packets. To avoid the influences of packets transmitted by another process, I add some codes to do the filtering for wpan-ping client and wpan-ping server. Do you consider this as a bug for wpan-ping? If yes, I'll submit the modification as a new patch for discussion, thank you all!
