Quad-port Ethernet

Has anyone used a quad-port Ethernet card, 1000GB, PCI Express? In
particular, we are looking at
http://www.intel.com/network/connectivity/products/pro1000pt_quad_server_adapter.htm.
We are currently using the two-port version of this card, that has
just one chipset on it; the four-port version has two such chipsets.
Other brands supported by QNX would be of interest, also.

Thanks,

Kevin
