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.

Does Sun still make ATM cards? As far as I remember I saw the last SBUS
cards a couple of years ago.
