You got it all wrong. The sender is sending packets with the same QoS
parameters; its the receiver thats trying to prioritize some packets
over the others. One would typically do this for the Hellos/KeepAlives
that are associated with a protocol, so that the  adjacency/peering
session are not timed out.
