How to enable ECMP flow based forwarding ?

I'm testing FreeBSD ECMP behavior by adding "options RADIX_MPATH" to my
kernel configuration (11-stable).
Now I can configure two identical routes toward 2 different next-hop: First
step achieved :-)
But it uses only the first entry and never uses the second one.
I've tried to shutdown the first next-hop router (then no more arp-reply
from this next-hop): But the ECMP FreeBSD router sticks to its first route
entry and never try the second entry :-(
Is there something else to enable (like RSS?) for having a real ECMP flow
based router ?
