hello, (sorry in case this is the wrong mailing list) while doing some network testing, I discovered that my FreeBSD (r304285, but likely earlier + released ones as well) sends out two (bytewise-)identical ICMP echo requests shortly after each other when I ping the broadcast (IPv4) address on an interface [tested with: tap,em,iwm]. This behaviour does not meet my expectations - is there any specific reason for this behaviour; it behaves well (sending out a single ICMP echo request) if I ping a unicast host. hannes
