dummynet cpu usage

[Evgenii Davidov]

Dear Luigi,

i've moved from RELENG_8 to RELENG_8_0 and now have a lot of idle cpu again:

0 root       -68    0     0K    72K -       0   0:31  0.00% {dummynet}

00030  2671994   474106017 pipe 6 ip from table(111) to any out xmit em0
00040  4495521  2942321163 pipe tablearg ip from any to table(2) in recv em0

 ipfw pipe show | wc -l
     504
