Without IP Fragmentation: add user selected buffer sizes + 80 bytes per socket

With IP Fragmentation: add user selected buffer sizes + 40 bytes + 100 bytes per socket + size of reassembly buffer(s)

Ethernet throughput numbers are calculated by timing the transmission of 1000 UDP packets containing 1460 bytes of data.
