You can disable the broadcom TOE removing the key on the motherboard. http://support.euro.dell.com/support/edocs/systems/pe2950/en/hom/html/jumpers .htm#wp1054670
Ciao. Andrea Renaud Allard <[EMAIL PROTECTED]> Sent by: [EMAIL PROTECTED] 05/09/2007 09.45 To misc@openbsd.org cc Subject bnx tcp offload Hello, I just have two Dell servers having broadcom netXtreme NICs with tcp offload engine activated (and locked on on) in the bios. I tried to use these servers to do an smtp gateway with spamd. When I activated spamd, connecting to port 25 worked but nothing more. After scanning with tcpdump, I saw that all packets passing through pf going to spamd and exiting had bad tcp checksum. The machine at the other end receiving these bad tcp checksum of course dropped them. For the moment, I solved the issue by using Intel em NICs. Packets passing not passing through pf had also about 50% packets with bad checksum too. Is there a software way to force the bnx driver to _not_ use the TCP offload engine without recompiling the driver?
