EoIP on CCR per core balancing

Good day.
From release notes to 6.24 CCR supports eoip per core load balancing:

What's new in 6.24 (2014-Dec-23 13:38):

*) ntp - fixed vulnerabilities;
*) web proxy - fix problem when dscp was not set when ipv6 was enabled;
*) fixed problem where some of ethernet cards do not work on x86;
*) improved CCR ethernet driver (less dropped packets);
*) improved queue tree parent=global performance (especially on SMP systems and CCRs);
*) eoip/eoipv6/gre/gre6/ipip/ipipv6/6to4 tunnels have improved per core balancing on CCRs;

I installed 6.30.1 on my CCR-1016, connected it via two links with RB2011, brouhgt up two tunnels, started a BW test on 2011 and saw that only one core was used on 1016 in EoIP decapsulation:

/ip address
add address=3.3.3.1/24 interface=ether6 network=3.3.3.0
add address=4.4.4.1/24 interface=ether8 network=4.4.4.0
add address=5.5.5.1/24 interface=tun1 network=5.5.5.0
add address=6.6.6.1/24 interface=tun2 network=6.6.6.0

What should I do to balance eoip traffic on different cores?
Thank you
