Dear all,

I am a beginner with DPDK. 
I just install it in fedora18 with two X540 Enthercards.

After compile it and run the testpmd I got the following message:
====================================================================

========================================================================
Although I can get into the testpmd command mode, but it seems EAL fails to bind the socket on 
the PCI device.
Therefore, when I run start tx_first and stp, no package forwarding as follow

=====================================================================

Done.
====================================================================

Can anyone tell me how to fix this?

Thank you very much.
