Hi,
Has anyone had experience playing with the 82572GI PCIe cards under FreeBSD?
We had bunch of cards from two vendors, a few server adapter cards, but most of
them
client adapter cards
(http://www.intel.com/network/connectivity/products/prodbrf/pro1000_pt_desktop_adapter.pdf)
They all had problems (hard to pin down the exact problem, but i suspect
auto-negotiation) under FreeBSD 5.4. We are using the em-5.1.5 driver from
Intel's
website that is meant for FreeBSD 5.x, and the cards are all recognized on
boot, and if I assign an IP, it appears to work (at least i could ping the
machine's own IP). However,
when they are connected to the rest of the network via 100Mbps switches, they
are not
able to ping any host on the network.
Sometimes, i could get the cards to work by plugging them into a different
100Mbps port and then back to the original port, and I also found that if i
have a gigabit port handy, i could connect the adapter to the GigE, and then
connecting to the 100Mbps would work.
The strange and not so funny thing is that a few cards have no problems, but
most of have this problem. I cannot quite tell whether i have a bunch of
defective cards (I guess I should test it under Windows), or maybe the 5.x
driver doesnt support these PCIe cards very well.
One thing I did that might shed some light is that I backed ported some stuff
from 6.2 em driver, and that really eliminated the trouble that I was having.
If anyone is interested, I'd be happy to post the code I backported.
Thanks,
Cheng
