Subject: [PATCH 3.2 49/59] ipv6: Need to export ipv6_push_frag_opts for
 tunneling now.

3.2.92-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: "David S. Miller" <davem@...emloft.net>

commit 5b8481fa42ac58484d633b558579e302aead64c1 upstream.

Since that change also made the nfrag function not necessary
for exports, remove it.

Fixes: 89a23c8b528b ("ip6_tunnel: Fix missing tunnel encapsulation limit option")
