[openib-general] RDMA enabled NICs- newbie

[Steve Wise]

As has been said already, there are two rnics running with the Open
Fabrics stack, the Ammasso 1100 and the Chelsio CXGB3 rnics.  Tom Tucker
and I are the maintainers of this code base (the iwarp branch).  

I hear NetEffect also has an 10Gb iWARP NIC.  As far as I know, they
don't have any support for the Open Fabrics iwarp branch yet. 

Steve.
