1、内核配置

cd kernelmake menuconfig配置如下：Device Drivers  
cd kernel
make menuconfig


配置如下：
Device Drivers
    USB support
        USB Gadget Support
             USB Gadget Drivers
                Ethernet Gadget (with CDC Ethernet support)
               
  • RNDIS support
             


    • RNDIS support 配置完成后重新编译kernel将在kernel/drivers/u***/gadget生成对应的ko文件
      2、拷贝ko到开发板

      为了避免modprobe加载驱动的时候，相关依赖的ko找不到，可以把kernel/drivers/u***/gadget下的所有ko拷贝到开发板/lib/modules/4.4.194下面（当然，大神可以忽略）。
      注意：4.4.194这个文件可能没有，没有的话自己手动创建（不一定是4.4.194，使用uname -r确认）

      3、加载g_ether驱动

      执行一下命令即可完成驱动加载：

    • depmod
    • modprobe g_ether.ko
    • 加载成功会有以下打印：

    • [   25.423705] using random self ethernet address
    • [   25.423890] using random host ethernet address
    • [   25.425511] u***0: HOST MAC d2:37:f3:a7:4b:42
    • [   25.425862] u***0:[root@rk1808:/lib/modules/4.4.194]#  MAC 16:ff:b3:46:ba:5f
    • [   25.425991] using random self ethernet address
    • [   25.426027] using random host ethernet address
    • [   25.426202] g_ether gadget: Ethernet Gadget, version: Memorial Day 2008
    • [   25.426231] g_ether gadget: g_ether ready
    • [   25.484903] IPv6: ADDRCONF(NETDEV_UP): u***0: link is not ready
    • 加载成功后使用ifconfig命令可以看到u***0这个网卡：
      4、测试网卡

      将开发板连接到PC(windows和linux都可以，这里以linux为例)，插上PC后，正常的话使用ifconfig可以看到多出一个网卡，这个网卡就是rk1808开发板：
    • ifconfig


    • ens33: flags=4163  mtu 1500

    上面的ens160u2c2就是连接的rk1808虚拟出来的网卡；
    5、通信测试

    将开发板和PC的网卡设置为同一个网段，然后测试是否可以ping通：
    开发板端：
    ifconfig u***0 192.168.0.100
    PC端
    sudo ifconfig ens160u2c2 192.168.0.101
    开发板ping PC：

    ping 192.168.0.101


    PING 192.168.0.101 (192.168.0.101) 56(84) bytes of data.
    64 bytes from 192.168.0.101: icmp_seq=1 ttl=64 time=0.674 ms
    64 bytes from 192.168.0.101: icmp_seq=2 ttl=64 time=0.853 ms

    64 bytes from 192.168.0.101: icmp_seq=7 ttl=64 time=0.581 ms
    测试正常！！！
    PC ping开发板：

    ping 192.168.0.100


    PING 192.168.0.100 (192.168.0.100) 56(84) bytes of data.

    64 bytes from 192.168.0.100: icmp_seq=8 ttl=64 time=0.682 ms
    测试正常！！！
  • RNDIS support
             


    • RNDIS support 配置完成后重新编译kernel将在kernel/drivers/u***/gadget生成对应的ko文件
      2、拷贝ko到开发板

      为了避免modprobe加载驱动的时候，相关依赖的ko找不到，可以把kernel/drivers/u***/gadget下的所有ko拷贝到开发板/lib/modules/4.4.194下面（当然，大神可以忽略）。
      注意：4.4.194这个文件可能没有，没有的话自己手动创建（不一定是4.4.194，使用uname -r确认）

      3、加载g_ether驱动

      执行一下命令即可完成驱动加载：

    • depmod
    • modprobe g_ether.ko
    • 加载成功会有以下打印：

    • [   25.423705] using random self ethernet address
    • [   25.423890] using random host ethernet address
    • [   25.425511] u***0: HOST MAC d2:37:f3:a7:4b:42
    • [   25.425862] u***0:[root@rk1808:/lib/modules/4.4.194]#  MAC 16:ff:b3:46:ba:5f

    • [   25.426027] using random host ethernet address

    • [   25.484903] IPv6: ADDRCONF(NETDEV_UP): u***0: link is not ready
    • 加载成功后使用ifconfig命令可以看到u***0这个网卡：
      4、测试网卡

    6、带宽测试

    利用iperf工具测试带宽：
    PC端执行：
    iperf -s -i 1       //以server模式启动，1s打印一次
    开发板端执行：
    iperf -c 192.168.101(电脑的ip地址) -i 1 -w 2M -t 120
    测试结果如下：

    6、带宽测试

    利用iperf工具测试带宽：
    PC端执行：
    iperf -s -i 1       //以server模式启动，1s打印一次
    开发板端执行：
    iperf -c 192.168.101(电脑的ip地址) -i 1 -w 2M -t 120
    测试结果如下：
