[OpenWrt] 23.05 在构建固件时，还能用回 iptables 么， nftables 感觉有些不太好用

在 menuconfig 里，似乎已经没有 iptables 能选了，openwrt 的 nftable 不知道是版本精简还是我自己语法问题..

root@openwrt:~# nft add table trouter
root@openwrt:~# 
root@openwrt:~# 
root@openwrt:~# 
root@openwrt:~# nft add chain trouter icmp_filter { type filter hook input priority 0 \; }
root@openwrt:~# nft add rule trouter icmp_filter iifname "eth0" icmp type echo-request drop
root@openwrt:~# 
root@openwrt:~# 
root@openwrt:~# nft add rule trouter icmp_filter iifname "br-lan" icmp type echo-request drop
root@openwrt:~# 
root@openwrt:~# 
root@openwrt:~# nft add rule trouter input iifname { "eth0", "br-lan" } icmp type echo-request counter jump icmp_filter
Error: Could not process rule: No such file or directory
add rule trouter input iifname { eth0, br-lan } icmp type echo-request counter jump icmp_filter
                 ^^^^^
root@openwrt:~# 
root@openwrt:~# nft add rule trouter input iifname eth0,br-lan icmp type echo-request counter jump icmp_filter
Error: Basetype of type network interface name is not bitmask
add rule trouter input iifname eth0,br-lan icmp type echo-request counter jump icmp_filter

                 ^^^^^

要是 iptables ，这事情早结束了。。。。
