+    ### 重要说明 ：脚本仅用于M7服务器，带有i2c standard tool工具的BMC使用
+    
+    一、脚本使用方法 V1.0
+
+        1、针对不同项目，请先修改脚本中的部分变量（ADC128电压传感器的分压系数，INA3221的分流精密电阻阻值）
+
+        2、为脚本增加可执行权限 chmod +x ./nicsensor.sh 
+
+        3、脚本命令格式 ./nicsensor.sh <pcie_slot> <chip_type> <chip_slave>
+            
+            参数说明：
+                pcie_slot : 网卡所在的PCIE槽位，填数字0，1，2，3，4，5
+                chip_type : 传感器芯片的类型，emc1413,adc128,ina3221
+                chip_slave: 传感器芯片的I2C地址（7bit）
+            
+            举例说明：读取PCIE 1 上网卡的adc128芯片， 芯片slave地址为0x1f
+                ./nicsensor.sh 1 adc128 0x1f
+
+        4、特殊命令
+
+            4.1 扫描服务器的PCIE slot 0 - 5上所有的I2C设备
+
+                命令: ./nicsensor.sh detect
+            
+            4.2 读取fru信息
+
+                命令： ./nicsensor.sh <pcie_slot> fru <chip_slave> read
+                举例说明：读取Ravel板卡的EEPROM中的FRU（0x57）
+                    - ./nicsensor.sh 5 fru 0x57 read
+
+            4.3 读取CPLD寄存器
+
+                命令： ./nicsensor.sh <pcie_slot> cpld <chip_slave> <i2c_cmd>
+                举例说明：读取cpld的寄存器 0x00 ,读2个byte 
+                    - ./nicsensor.sh 5 cpld 0x10 "i2ctransfer -y 13 w1@0x10 0x00 r2"
+
+
+    二、5280M7 PCIE槽位和PCA9548的channel关系
+
+        5280M7的PCIE槽位和PCA9548/9546没有确定的对应关系，取决于使用的riser卡。根据一般情况选择的Riser卡，对应
+        情况如下：
+
+            PCIE 0 = i2c bus 12 , 9548channel1(0x02)
+            PCIE 1 = i2c bus 12 , 9548channel2(0x04)
+            PCIE 2 = i2c bus 12 , 9548channel3(0x08)
+            PCIE 3 = i2c bus 13 , 9548channel1(0x02)
+            PCIE 4 = i2c bus 13 , 9548channel2(0x04)
+            PCIE 5 = i2c bus 13 , 9548channel3(0x08)
+
+        可以根据实际情况选择性的修改脚本中的 start_detect_device 和 set_configuration 两个函数
+    
+    三、M7 sysadmin用户 SSH打开方法
+
+        5280M7服务器默认不开启SSH，且串口通常有较多干扰打印，因此推荐使用SSH来执行脚本，刷新BMC镜像后需要重新配置
+
+        1、打开M7 BMC的串口，可通过串口线或者IPMI SOL带外登入
+
+            使用IPMI SOL的前提环境：可与BMC网络连接，且电脑上有ipmitool工具
+            SOL登陆方法：
+                1）将SOL串口源切换到BMC：
+                    ipmitool -I lanplus -H <bmcip> -U admin -P admin raw 0x3c 0x2c 0x02 0x01
+                2）打开SOL：
+                    ipmitool -I lanplus -H <bmcip> -U admin -P admin sol activate
+                备注：<bmcip> 为目标BMC的ip地址，请自行更改为对应的ip地址
+
+        2、登录进入bmc的linux系统
+
+            bmc linux系统的默认用户名/密码 ：sysadmin/superuser
+        
+        3、在BMC的linux系统下执行命令
+
+            1） cp /etc/defconfig/ssh_server_config_with_sysadmin /etc/ssh/sshd_config
+            
+            2） /etc/init.d/ssh restart
+
+            执行完毕后，就可以使用ssh登录BMC了
+
+    四、常见问题
+
+        1、脚本执行时出现大量的 Error
+
+            由于M7服务器的I2C设计有PCA9641作为I2C仲裁器，脚本执行过程中可能会被9641强行断开I2C连接，造成大量的
+            脚本Error，这种时候重新执行脚本即可
+
+        2、不建议使用该脚本进行压力测试
+
+            由于BMC shell的版本非常原始，没有集成高级的命令行工具，因此处理数值时采用了复杂的脚本逻辑进行执行，处
+            理效率较低。另外由于9641芯片的存在，不能保证压力测试的正常执行。
