[缺陷描述]：
当前通过iso安装的龙芯系统不支持connector

查询进程目录下无connector目录
# ll /proc/net/connector
ls: cannot access '/proc/net/connector': No such file or directory

connector相关config：
# grep -i connector /boot/config-4.19.190-3.an8.loongarch64
# CONFIG_CONNECTOR is not set

[期望结果]：
龙芯系统支持connector

[实际结果]：
龙芯系统不支持connector

[初步分析]：
龙芯系统connector编译开关未打开，请开发同学确认是否可以支持connector
Comment 1 ticat loongson_group 2021-12-21 20:14:48 UTC 
分析：
内核配置项未打开
解决：
CONFIG_CONNECTOR=m/y
Comment 2 yangyinglu loongson_group 2021-12-27 10:43:39 UTC 
龙芯最新内核支持配置文件CONFIG_CONNECTOR，并在系统中导出此变量

root@loongson-pc:/home/loongson# ls /proc/net/connector 
/proc/net/connector
Comment 3 shanxifanshi alibaba_cloud_group 2022-01-11 18:41:20 UTC 
目前rc2版本还是不支持connector，持续关注
# ls /proc/net/connector
ls: cannot access '/proc/net/connector': No such file or directory
Comment 4 yangyinglu loongson_group 2022-01-11 20:46:43 UTC 
最新版本比RC2新，服务器内核最新版本还没有评审。
Comment 5 shanxifanshi alibaba_cloud_group 2022-01-21 18:10:29 UTC 
使用最新的龙芯8.4 GA ISO安装系统后进行验证，该问题依然未解决
# uname -r
4.19.190-4.an8.loongarch64

# ls /proc/net/connector
ls: cannot access '/proc/net/connector': No such file or directory

# grep -i connector /boot/config-4.19.190-4.an8.loongarch64
# CONFIG_CONNECTOR is not set
