[Tinyos-devel] purpose of the Packet.clear() function

Hi!

I think there should be, but it is unfortunately not used. If a user
requests for example acknowledgment via the PacketAcknowledgement
interface, then it is not clear when that flag will be cleared if the
message_t is reused. So the Packet.clear should be called to reset
everything to their defaults in the header and metadata, this should
be especially important between the serial and radio interfaces.
