dual pci nic with bridging
Anybody have experience with a PCI-based dual-interface NIC that does hardware bridging? This would be for a traffic monitoring application, so the host cpu must be able to snoop traffic. Software bridging is not feasible. Thanks for any pointers. -- Brian St. Pierre ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
