9.5.9 raw_ethernet_bw
raw_ethernet_bw calculates the BW of SEND between a pair of machines. One acts as a server
and the other as a client. The server receive packets from the client and they both calculate the
throughput of the operation. The test supports features such as Bidirectional, on which they both
send and receive at the same time, change of mtu size, tx size, number of iteration, message size
and more. Using the "-a" provides results for all message sizes.
