防火墙运行firewall-cmd --reload报错，针对itx3568开发版

针对嵌入式开发版在进行firewall-cmd --reload报错如下

firewall-cmd --reload
Error: COMMAND_FAILED: 'python-nftables' failed:

原因：可能是ipv6_rpfiltter的问题，

解决办法：修改防火墙配置文件/etc/firewalld/firewalld.conf将ipv6_rpfiltter=yes改为ipv6_rpfiltter=no，然后再firewall-cmd --reload仍然报错的话，则需要编译内核，开启NF_filter方面的配置项即可解决问题
