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 ($Revision: 4362$)

Any suggestions is much appreciated.
