[dpdk-users] 82575EB binding is failed

[mariappan.rajendran]

Hi Team,

I am running DPDK 2.2.0 on top of Ubuntu 14.04 and my server have 2 NIC cards. With this, when I am trying to bind my non active 82575EB NIC to DPDK, but after giving the  PCI ID, the server hanged. Below are the logs from setup.sh.

Option: 23

Network devices using DPDK-compatible driver
============================================
<none>

Network devices using kernel driver
===================================
0000:03:00.0 '82575EB Gigabit Network Connection' if=eth0 drv=igb unused=igb_uio *Active*
0000:03:00.1 '82575EB Gigabit Network Connection' if=eth1 drv=igb unused=igb_uio 

Other network devices
=====================
<none>

Enter PCI address of device to bind to IGB UIO driver: 0000:03:00.1
OK

Press enter to continue ... (after binding system resides in this same screen)

I also ensured that this NIC is supported or not by DPDK by browsing  the rte_pci_dev_ids.h file, it is there, but still the binding is failed. Below are the logs.

#define E1000_DEV_ID_82575EB_COPPER             0x10A7

Please let me know what could be the problem, and how to resolve it.  Your help is much appreciated.

Thanks,
Mari.
