Thanks for you reply Jack, 

This box working as a router with up to 60 kpps traffic rate , I believe
there is enough flows to see both queues running. 

# netstat -I em0 -w 1
            input          (em0)           output
   packets  errs idrops      bytes    packets  errs      bytes colls
     60356     0     0   61659974      46803     0   15527523     0
     56273     0     0   56429189      44278     0   15199658     0
     55405     0     0   55408969      43654     0   14978427     0

Anyway, will try to rebuild em module with 

CFLAGS += -DEM_MULTIQUEUE

and with LEGACY stuff commented out in src/sys/modules/em/Makefile tomorrow.

Is this enough or should I put define in the beginning of src/sys/dev/e1000/if_em.c ?
