/*
tcp_perf example

Using this example to test tcp throughput performance.
esp<->esp or esp<->ap

step1:
    init wifi as AP/STA using config SSID/PASSWORD.

step2:
    creat a tcp sever/client socket using config PORT/(IP).
    if sever: wating for connect.
    if client connect to sever.
step3:
    send/receive data to/from each other.
    if the tcp connect established. esp will send or receive data.
    you can see the info in com port output.
