ipset hash:net,iface - can not add more than 64 interfaces

[Марк Коренберг <socketpair@xxxxxxxxx>]

for i in `seq 0 70`; do ip link del dummy$i; done;
for i in `seq 0 70`; do ip link add type dummy; done;
for i in `seq 0 70`; do ipset add qwe 0.0.0.0/0,dummy$i; done;

Reveals the problem. Only 64 records can be added, but there are no
obvious restrictions on that. I s it possible to increase the limit ?
