 版本说明：
---V1.22 --
+--V2.1 --
+  2021-11-30
+  1) 解决bond模式为3时出现段错误问题。
+    问题描述：网卡监视程序启动过程中存在段错误
+    问题分析：bond模式3由于对bond模块源码进行了修改，导致/proc/net/bonding/目录下新增LINXNETHA目录。程序在处理时没有处理目标为目录情况，导致出现空指针情况，之后在对比字符串（strncmp）时，使用空指针从而导致段错误。
+    解决办法：增加对目录的过滤，当目标为目录时退出线程。
+--V2.0 --
   2020-07-09
   1）根本南瑞郭海龙要求进行接口的修改
     取消之前libman.so动态库和proc_inv.h头文件，改为新的libproc_common.so动态库，同时增加include头文件目录
