Feature request: <allow to request specific ipv6 prefix>

[try496]

What would you like to see in luci?

odhcp6c has merged the commit that supports this feature. If the ISP supports this feature, it would allow obtaining a specific IPv6 prefix. I hope that luci will addd aan option for it.

/After testing, it has been confirmed that by requesting a specified length of an IPv6 prefix and filling in the corresponding address, one can obtain the desired IP address or prefix

[try496]

Perhaps the text could be updated to better illustrate this point.

That setting has only recently been changed in odhcp6c.

Previously.

Usage: odhcp6c [options] <interface>

Feature options:
...
    -P <length> Request IPv6-Prefix (0 = auto)

Perhaps we can wait until the 24.10 branch is merged to update the description.

[systemcrash]

to what?

[systemcrash]

That's in main, not in snapshot.

openwrt/openwrt@b0312c1 The latest commit has been merged into the snapshot.

Go ahead and cherry-pick it to snapshot (24) also.

If it's in main, we can at least modify this string in main here.

Agreed that we should use a descriptor, and not title.
