I've checked PF_RING documentation and pf_ring_open code. Both studies lead to the conclusion that there is no error return. So it is impossible to get the reason of the error from the library.

I think we should close this ticket for now.

Maybe we can just add a more verbose error message. Something like:

[7705] 9/9/2013 -- 10:58:22 - (source-pfring.c:409) <Error> (ReceivePfringThreadInit) -- [ERRCODE: SC_ERR_PF_RING_OPEN(34)] - opening eth1 failed: pfring_open error. Check if eth1 exists and pf_ring module is loaded.
