| 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. |
