Bad UDP packets from SL client

Working on writing an SL packet dissector for Ethereal and noticed that the packet length for some UDP packets originating from the client where flagged as having invalid checksums:



This happens with a large variety of packets, PacketAck, StartPingCheck, CompletePingCheck, ect.. The only thing I can tell that might be the culprit is that the packets are not zero padded to a word boundry, which changes the length field in the UDP header, and thus the checksum.

In the end, this could effect the protocols network performance a bit, since either the kernel has to go through and correct the padding, length, and checksum, or something along the way is just gonna drop it as invalid.
