Am I right? please read the mailing list archive again and understand my posts about the packet types. The host can't choose the right packet type. So let the link manager do this job and allow it to use whatever packet type it wants. > When I do this and I measure the udp packet > throughputs, the throughputs I get are all over the > place.

If yes, look at it and keep in mind that DM1 is always allowed and required.
