Hello,
I'm trying to write an ethernet level network tester using libpcap 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. 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 writing this on a FreeBSD 4.4R machine using ti (3Com) and sk (SysKonnect) cards (either/or... preference to the 3Com's since I have a lot of them). I've tried on the freebsd-net mailing list, and found that the ti driver has an opmode to "RX_BADFRAMES", but when I enabled it, I got the same results. Other opmodes actually worked, so I don't know if the card is ignoring the opmode, or if there are other checks going on somewhere else. If anyone knows how I might be able to get the bad packets to examine them, I'd much appreciate it. -- >-=-=-=-=-=-=-<>-=-=-=-=-=-<>-=-=-=-=-=-<>-=-=-=-=-=-<>-=-=-=-=-=-=-< Ryan Mooney [EMAIL PROTECTED] <-=-=-=-=-=-=-><-=-=-=-=-=-><-=-=-=-=-=-><-=-=-=-=-=-><-=-=-=-=-=-=-> - This is the TCPDUMP workers list.
