Subject: [IP6TUNNEL]: Allow to create IP6 tunnels in net namespaces.
X-Git-Tag: v2.6.26-rc1~1138^2~23
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=554eb27782d4bb79e0a286a08ecafb81f758058c;p=linux-2.6

[IP6TUNNEL]: Allow to create IP6 tunnels in net namespaces.

And no need in some IPPROTO_XXX enabling, since ipv6 code
doesn't have any filtering.

So, just set proper net and mark device with NETNS_LOCAL.
