IPv6 for IPVS is mainline, see:
commit e7ade46a53055c19a01c8becbe7807f9075d6fee
Author: Julius Volz <juliusv@xxxxxxxxxx>
Date: Tue Sep 2 15:55:33 2008 +0200
this contributes 2 (+ u16 af) + 3 * 12 (union nf_inet_addr instead of
__be32) = 50 bytes / connection, other changes contribute apparently
more.
Cheers,
Hannes
