Sended new set of patches, 3rd one being the change of mtu handling in
UDP access. It takes high mtu but assumes that packet size in streaming
is quite constant and adjusts the mtu if received packets are way
smaller that mtu. The patch has harriston-stetson limit of 1500, but it
should give the idea of approach.
