Hi,
Im using a built in re(4) card and it seems like its causes data-
corruption as soon as it gets some load (or after a few hours online)
The machine is running FreeBSD 7.0R:
FreeBSD ninja 7.0-RELEASE FreeBSD 7.0-RELEASE #0: Wed Apr 16 22:49:15
CEST 2008 peter@ninja:/usr/obj/usr/src/sys/NINJA amd64
(using a RELENG_7 kernel updated today)
If I download alot of files with wget or something everything works
fine for a while until the download just stalls and tcpdump reports
"bad cksum"
13:04:25.839408 IP (tos 0x0, ttl 64, id 23912, offset 0, flags [DF],
proto TCP (6), length 1500, bad cksum 0 (->f40a)!) host1.http >

<nop,nop,timestamp 2316944721 2174233192>
and so on
again and again until the connection times out.

A strange thing is that encrypted data seems to work better than
plaintext. https works for a longer time (after boot) then http for
example.
