[CentOS] Recommendations for Infiniband with CentOS 6.7

[Pat Haley]

We have a new install of CentOS 6.7 with infiniband support installed. 
We can see the card in hardware and we can see the mlx4 drivers loaded 
in the kernel but cannot see the card as an ethernet interface, using 
ifconfig -a.  Can you recommend an install procedure to see this as an 
ethernet interface?

Thanks
