I have a Dell R710 running Debian Linux 6.0 (Squeeze). I installed a QLogic QLE8152 CNA in the PCI-E riser today and I have been trying to get the CNA's ethernet layer to come up after I put a fiber loop on it; I also scoped it with a light meter, and the SFP+ transceiver is getting the correct amount of light. The whole time I have been working on this problem, the lights on the CNA are blinking green at a rate of about 1 flash every 3 seconds.

When I plug the fiber into a Juniper EX4500 10GE in a rack next to it, the Juniper's link stays down as well.

I have to confess that this is my first wrangling with a CNA, so perhaps I'm doing something fundamentally wrong, but here is what I have found so far...

First the basics...

lspci -v shows that the card is properly installed (physically)

The output from ethtool shows that eth4 is the QLE8152...

[mpenning@Finger ~]$ sudo ethtool eth4

Finally, I tried modprobe -r qlge; modprobe -r qla2xxx and then modprobe qla2xxx; modprobe qlge to kick the system again... I don't see a smoking gun in /var/log/messages...

Any assistance getting a link up on this is greatly appreciated...
