[Tinyos-help] About the packet with different length

[Michael Schippling]

Different message payloads can be of different lengths, up to the maximum.
The Receive layer doesn't know what sort of message it is dealing with,
so it does some integrity checks based on header information and uses
the length to figure out where the CRC is.
