how to disable completely ipv6 on openwrt
You can't disable IPv6 completely. Too many kernel / firewall / whatever modules are nowadays dual-stack, so some ipv6 support is always compiled in.
The "global" config option, which was already faulty/buggy, was removed last year.
You can disable address allocation etc. via config options, and prevent practical IPv6 usage, but there is still IPv6 support infra present.
