Subject: [PATCH 3.2 32/95] net: ipv6: set route type for anycast routes

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

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

From: David Ahern <dsa@...ulusnetworks.com>

commit 4ee39733fbecf04cf9f346de2d64788c35028079 upstream.

Anycast routes have the RTF_ANYCAST flag set, but when dumping routes
for userspace the route type is not set to RTN_ANYCAST. Make it so.

Fixes: 58c4fb86eabcb ("[IPV6]: Flag RTF_ANYCAST for anycast routes")
