Re: [PATCH] build: always set CONFIG_IPV6
I find strange any conversation around disabling IPv6 these days, regardless the reason. It should be mandatory even if some ISPs don't have it enabled yet. How can one say that IPv6 may be unwanted ? If there is such scenario there is something very wrong there. What should be fixed is the lack of IPv6 in the network or from the ISP, not to remove it from any builds, specially in a OpenWrt build. There is not harm to keep it as is and if there is no IPv6 from the ISP nothing bad will happen to the router and everything else will remain working as expected in IPv4. If there was a reason in the past people were removing it was for devices with limited amount of flash (4MB generally), but I believe that any device with a minimal of 8MB it is already enough to not have to remove IPv6 from the build.

Would it make sense to simply always build with IPV6 support and have the CONFIG_IPV6 flag repurposed to have the defaults for the network interfaces and kernel sysctls set to disable IPV6 as much as possible? This might make sense in environments where any IPV6 support is unwanted. Still many people have no IPV6 at home or at work and hence better not have it configured at their local network nor router.
