Hi there, I am struggling with a weird packet dropping situation.  My envir=
onment is pfring zc with intel x520 nic. Only started a pfcount to count re=
ceived packets by one of 10Gb port of this card. Everything went smoothly, =
except when a burst traffic up to 2Gb came in, ifconfig reported thousands =
packets were dropped. The reason I called it weird was when the traffic rem=
ained on the level of 2Gb, no packet dropped any more.

Any comment?
