Hi,

Here is the lscpi output -

81:00.0 Ethernet controller [0200]: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection [8086:10fb] (rev 01)
81:00.1 Ethernet controller [0200]: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection [8086:10fb] (rev 01)
84:00.0 Ethernet controller [0200]: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection [8086:10fb] (rev 01)
84:00.1 Ethernet controller [0200]: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection [8086:10fb] (rev 01)

I am using Fedora 18, DPDK version 1.5.0r1

The first two ports (as in lspci output) are connected to the switch and Linux is able to ping using these.
When they are in linux control, I see that auto negotiation is done for 10 Gbps
I unbind 81:00.0 and apply igb_uio

Now when I start the DPDK application, I get the error which I am attaching with DEBUG set to y.
Somehow DPDK is not able to recognize the NIC.

Any hints if someone has encountered a similar issue.

Regards
-Prashant
