luci-mod-network: update dhcpv6_pd_min_len values

[Alphix]

odhcpd will allow a greater range of PD prefix lengths, so update the UI to reflect this.

https://github.com/openwrt/odhcpd/pull/359

The question is if we should go for:

so.placeholder='62';

or:

so.default='62';
so.optional=true;

The disadvantage of the latter is that it'll remove the option if the user sets "62" (and then it'll change if we change the default in odhcpd)....

[systemcrash]

the latter with placeholder. we try and synch changes anyway.

the latter with placeholder. we try and synch changes anyway.

Instructions unclear. Segfault. Should I go for default, optional and placeholder or...what?

[systemcrash]

as it is now :)

[Alphix]

@systemcrash ok, and the PD change is in odhcpd master and 25.12 now, so should be ok to go in?

Is that commit in openwrt/openwrt yet?

[GoetzGoerisch]

Yes https://github.com/openwrt/openwrt/commit/3b58539817a99dc940cd2bb337ad61896a291aa9

[GoetzGoerisch]

This needs to be backported to 25.12 if I'm not mistaken?

[systemcrash]

picked. Thanks :)
