Zusammenfassung:	Performs simple Path MTU Discovery to target hosts.;;TCP or UDP packets are sent to the host with the DF (don't fragment) bit set and with varying;amounts of data. If an ICMP Fragmentation Needed is received, or no reply is received after;retransmissions, the amount of data is lowered and another packet is sent. This continues until;(assuming no errors occur) a reply from the final host is received, indicating the packet reached;the host without being fragmented.;;Not all MTUs are attempted so as to not expend too much time or network resources. Currently the;relatively short list of MTUs to try contains the plateau values from Table 7-1 in RFC 1191, 'Path;MTU Discovery'. Using these values significantly cuts down the MTU search space. On top of that,;this list is rarely traversed in whole because: * the MTU of the outgoing interface is used as a;starting point, and * we can jump down the list when an intermediate router sending a;'can't fragment' message includes its next hop MTU (as described in RFC 1191 and required by;RFC 1812)
