Subject: dhcpv6-ia: fix preferred and valid lifetimes in ubus ipv6leases
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f61964c66be050716089d31f13688c1ab382f0b7;p=project%2Fodhcpd.git

dhcpv6-ia: fix preferred and valid lifetimes in ubus ipv6leases

Since commit 6db312a698e920ff61505ef1f42469880829774d the preferred and
valid lifetimes of the addresses/prefixes is based on the configured leasetime;
as a result the displayed preferred and valid lifetimes need to be
calculated based on the assignment lifetime as this is set to the lowest
valid lifetime of the addresses/prefixes.
