I wonder if there are some spare bits inside the flags
member of ip_vs_scheduler that could be used for this purpose?
Otherwise, I'm fine with this, we can juggle things around
later to use the other bits in supports_ipv6 for other things
if and when the need arises.
Here is a version that applies against lvs-2.6

IPVS: Add IPv6 support flag to schedulers
Add 'supports_ipv6' flag to struct ip_vs_scheduler to indicate whether a
scheduler supports IPv6. Set the flag to 1 in schedulers that work with
IPv6, 0 otherwise. This flag is checked in a later patch while trying to
add a service with a specific scheduler.
