Hello, I'm trying to write an ethernet level network tester to test a wireless gigabit product the company I'm working for has developed. I need to be able to get packets off a Gig-E interface that have bad CRC checksums so I can see how badly mangled they are. I've tried using pcap and ng_ether int: lowerboth of which are giving me just the "good" packets. Right now they are being discarded somewhere below the bpf interface. I'm not sure where, I've read through a bunch of the *if* code, but I don't see it there. I did see some stuff in the 100Mb cards, but thats not really going to work here, since I'm pushing ~600Mb/s on the box doing the packet generation.. I'm using ti and sk cards (either/or...) If anyone knows how I can get the bad packets to examine them, I'd much appreciate it. Thanks. -- >-=-=-=-=-=-=-<>-=-=-=-=-=-<>-=-=-=-=-=-<>-=-=-=-=-=-<>-=-=-=-=-=-=-< Ryan Mooney ryan@pcslink.com <-=-=-=-=-=-=-><-=-=-=-=-=-><-=-=-=-=-=-><-=-=-=-=-=-><-=-=-=-=-=-=-> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
