vendors, for some reason, don't wire them tothe
pci-x bus. Most supermicro boards wire the emtyan
controllers to the 32bit/33mhz bus and the

the broadcoms to a shared 1x PCI-E, both ofwhich

not capable of running full gigabit rates.

The Intel card would be an INTEL Pro1000MF,
right? This would be quite
expensive (~ EUR 430), but good performance and
stability would warrant
that.
ATM, we are using the onboard controller
(Broadcom BCM5704C wired to the
pci-x bus). I did not have opportunity to do
performance measurements,
but we do have problems with our Linkpro
1000SX/1000TX converters, the
3rd of which has already died.
That's why i want to give a PCI-X card with
fiber interface a try.
No, that would be the 1000MT, the MF is a fiber
card I believe. They are about US$120. in the US.
How do you know its wired to the PCI-X bus, since
I don't believe that the controller has a way of
reporting the way that the intel controller does?
What MB do you have?
Also keep in mind that the bge driver is a piece
of crap; driver quality is a much more telling
factor in these free OS's than the card in many
cases. The EM and FXP are the only drivers worth
anything (mainly because neither were written by
mass-driver mill man Bill Paul).
After having fixed bugs in the bge driver I must stress
how wrong this statement is for the bge driver. Bill
Paul may or may not have been associated with the bge driver,
whether he was or not is immaterial since the bge driver is
basically a port of the broadcom-supplied Linux driver,
the code is Broadcoms mostly, with hunks of Broadcom
code removed (like that dealing with the PHY's) when it
was too difficult to port. (apparently) The quality of
the Broadcom driver isn't Bill Paul's, it's Broadcoms.
No, I can assure you that the reason the Broadcom
chips work like crap under FreeBSD is not due to Bill Paul,
it is because the Broadcom hardware iteself is pure, unadulterated,
stinking, bull crap. It is crappy even under the supported operating
systems like Windows, it's craptitude reaches new heights on
the crap pile. Broadcom missed their calling as an ethernet
chipset designer, they should have gone into making vacuum
cleaners, as they would certainly be the suckiest ones in
that business.
