Subject: 6in4: support multiple additional user prefixes
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e83bc5e3c7531fe1a4ac090d49235274ba04b417;p=openwrt%2Fstaging%2Fblocktrron.git

6in4: 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 routed IPv6 prefixes.

Implements feature request FS#1361.
