Last time we tried this driver (around 4.6-RELEASE) we had massive problems with the chipset occasionally incorrectly checking TCP checksums... which caused the interface to lock up. I think someone posted a workaround to disable the hardware checksum checking feature - but we only had these cards onboard in our production servers. Maybe its corrected now... who knows?? By the sounds of it you aren't having any issues :-) ----- Original Message ----- From: "Don Bowman" <don@sandvine.com> To: "'Jamie Heckford'" <jamie@jamiesdomain.org.uk>; <freebsd-stable@FreeBSD.ORG> Sent: Thursday, October 17, 2002 3:28 PM Subject: RE: Compaq GIGA NIC > > From: Jamie Heckford [mailto:jamie@jamiesdomain.org.uk] > > > > Urgh - The broadcom chips perform terribly! > > > > We put Intel cards into the riser slots on all our compaq > > servers......
