Reset used when the K6 fly or crash and can not built the normal connection,so can not work. Reset to initialize
the module to resume normal operation.
When working as TCP Client, K6 connects to TCP Server actively. When start Reset function, K6 try to connect to
TCP Server for 30 times. If failed, K6 will restart automatically. By default, it won’t be chose.

Index
Index is to resolve the problem that under TCP server mode, K6 can not divide the data sources or send data to
special client when user have more than 2 client to connect the K6.
At most there can be 16 links when the K6 in the TCP server mode. The max number can set from 1to 16 as you
want. Here we take the default number is 16 as example. Server send data to 16 clients, or the server receive the data
from 16 clients, open the Index, mark to divide the different clients and user can recognize the data sources according
to the mark, meanwhile send different data to special clients.
