I test to ping to few other FreeBSD boxes, and still produce the same result like below, regardless either using em or bce, or changing the connected interface at Cisco switch that used by OpenBSD box. This is default installation of FreeBSD and OpenBSD. By the way, do syslog server (under FreeBSD or OpenBSD has limitation to receive more than 3000 messages per second? >From Cisco switch to FreeBSD box: #ping 10.100.3.73 repeat 1000 Type escape sequence to abort.
