The marconi HE cards have the same format although they have no promiscous mode (although it would be easy to configure all unused connections to receveive to a free receive group, the question is whether you want this (350000/packets per second for OC3)). My driver allows you to receive cells (i.e. AAL0) on any of the supported connections. BMS>Is there any open source support for the SunATM PCI cards?

As far as I remember I saw the last SBUS cards a couple of years ago. harti -- harti brandt, http://www.fokus.gmd.de/research/cc/cats/employees/hartmut.brandt/private brandt@fokus.gmd.de, brandt@fokus.fhg.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
