This directory contains two family of drivers:

- PF_RING_aware/
Standard drivers that have been enhanced with PF_RING native support.
In order to exploit it, you need to do "insmod pf_ring.ko transparent_mode=1".

These drivers allow you to use the NIC for general purpose networking
while increasing the packet capture speed. Note that if you do
"insmod pf_ring.ko transparent_mode=2" the card will divert all incoming
packets to PF_RING thus you will not be able to use the card for networking
but only for packet capture. The advantage of this mode, is that with
respect to "transparent_mode=1" the packet capture speed is increased.


- DNA/
DNA (Direct NIC Access) drivers that allow applications to completely
bypass the kernel and access the card directly for maximum speed. This
means that an application sitting on top of the DNA driver can both send
and receive packets only using the PF_RING API, with no general purpose
networking (e.g. ping or web surfing) support. DNA drivers are limited
to selected network adapters. Please check its availability prior to
use them.
