Thank you for the replies Yes I am using the e1000e-1.0.15 driver that comes with the pf_ring codes.
# ethtool -g eth6 Ring parameters for eth6: Pre-set maximums: RX: 4096 RX Mini: 0 RX Jumbo: 0 TX: 4096 Current hardware settings: RX: 256 RX Mini: 0 RX Jumbo: 0 TX: 256 I was using nprobe v4.0 to test pf_ring. The only thing I did different to compile nprobe was adding "-lpfring" to the library flags. I tried changing transparency mode when loading the module but I am still getting the same result. Under /proc/filesystems I did not see pf_ring anywhere... But "lsmod" shows pf_ring is used by 2 (processes?) when I turn on nprobe on the interface that has the modified driver. Here is a tail of /var/log/messages [PF_RING] Welcome to PF_RING 4.4.0 ($Revision: 4362$) (C) 2004-10 L.Deri <[email protected]> [PF_RING] registered /proc/net/pf_ring/ NET: Registered protocol family 27 [PF_RING] Ring slots 4096 [PF_RING] Slot version 12 [PF_RING] Capture TX Yes [RX+TX] [PF_RING] Transparent Mode 0 [PF_RING] IP Defragment No [PF_RING] Initialized correctly device eth6 entered promiscuous mode Any suggestions is much appreciated.
