Subject: odhcp6c: support multiple additional user prefixes
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=66222dd92b3bdb0f035a4ab0370796cfdcdf8593;p=openwrt%2Fstaging%2Fnbd.git

odhcp6c: support multiple additional user prefixes

Support configuration in the form...

    list ip6prefix 2001:db8:1234::/64
    list ip6prefix 2001:db8:5678::/64

... to allow specifying multiple additional IPv6 prefixes.

Implements feature request FS#1361.
