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 ?
