In order to reproduce this here, could you tell me if you use

Producer linux-2.6.22 -> Receiver 2.6.22
Producer linux-2.6.31 -> Receiver 2.6.31

I use the above setup.

Then frames are sent on wire but not received

(they are received via  mc loop, internal stack magic)

We are talking about two machines running 2.6.22 or 2.6.31. There is no
magic mc loop between the two machines. -L was not used.

I have no idea how you run the test then, and how are computed time deltas.

Are you clocks synchronized to less than one us ? How is it done ?
