multihome with udp6 doesn't work

Description
I have multiple IPv6 tunnels and Openvpn answers always on the primary route.
With --multihome I get:
Jan 28 11:37:22 openvpn(server)[17978]: read UDPv6 [NO-INFO]: Connection
refused (code=146)
Jan 28 11:37:24 openvpn(server)[17978]: read UDPv6 [NO-INFO]: Connection
refused (code=146)
Jan 28 11:37:26 openvpn(server)[17978]: read UDPv6 [NO-INFO]: Connection
refused (code=146)
Jan 28 11:37:29 openvpn(server)[17978]: read UDPv6 [NO-INFO]: Connection
refused (code=146)
I don't know what code=146 means but I think multihome is not properly implemented for IPv6. tcp6-server is ok.
Why is multihome not enabled by default? (If it would work) I think everyone could use it (on Linux).
My Openvpn-version: openvpn-201102.tar.gz from here: ftp://ftp.secure-computing.net/pub/FreeBSD/ports/openvpn-devel/
compiled for mips.

Basically the fix is a 1-liner:
sed -i /setsockopt/s/IPV6_PKTINFO/IPV6_RECVPKTINFO/
, preparing a patch with additional defensive code around setsockopt() failures.

sorry, testing lasts longer than expected, my primary testing device broke down with other problems. I tested this on a router with two tunnelbroker ipv6-gateways and addresses from 3 different routed subnets. Everything is working as expected.

Based on the comment from 'the2masters', moving this one to fixed.
Commit f3ecd33c7c09 seems to be HEAD of the 201102 snapshot.
