Subject: Add support for unspecified IPv6 gateway address
X-Git-Tag: accepted/tizen/unified/20220524.050423^0
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F92%2F275092%2F1;p=platform%2Fcore%2Fconnectivity%2Fnet-config.git

Add support for unspecified IPv6 gateway address

Unspecified gateway address("::") is not permitted
when setting routing table.
So, if this value is passed, it must be handled appropriately.
