new c69ec94 Modifying the ping command
c69ec94 is described below
commit c69ec94d13dfec24d55345af462dd1c4a7f0fa47
Author: xuewenliang <xuewenli...@xiaomi.com>
AuthorDate: Mon Mar 14 16:12:11 2022 +0800
Modifying the ping command
1、Round trip times in the ping command range from millisecond to subtle
2、Add statistics on RTT related min/avg/Max/mdev in ping program
3、The ping command supports ctrl+c interruption operations
