I find in dpdk official hardware support list, it only list one ConnectX-3 Pro card which is an Ethernet card. Here is the hardware support list link: http://doc.dpdk.org/guides/nics/mlx4.html#supported-nics

The simplest way to answer that question on your own is to find the pci information with lspci.
Then lookup card in the tables in the source code.  That gives you the definitive answer.

Since Mellanox uses bifurcated mode you also have to have the matching Linux kernel driver.
