You seem to have gotten further than I did, I could not get a driver to recognize the card I was trying to use. 

Our current approach has been to switch to Solaris. Our options are more plentiful there, and coverage for various hardware seems more complete. 

>From your dmesg output, it looks like the ethernet device should be there. Try "ifconfig -a". You should see a new device called mlxen0: My plan was to hard configure the IB links in the rc.conf file like: 

ifconfig_mlxen0="inet netmask"

Did you manage to bring up a mellanox NIC with qsfp port as an ethernet 
I'm facing exactly the same issue. 

mlx4_core0: <mlx4_core> mem 0xfbd00000-0xfbdfffff,0xf9800000-0xf9ffffff 
irq 16 at device 0.0 on pci4 
mlx4_core: Mellanox ConnectX core driver v2.1 (May 28 2015) 
mlx4_en: Mellanox ConnectX HCA Ethernet driver v2.1 (May 28 2015) 
mlxen0: Ethernet address: 00:21:cc:49:48:93 
mlx4_en: mlx4_core0: Port 1: Using 8 TX rings 
mlx4_en: mlx4_core0: Port 1: Using 8 RX rings 

Forward thanks for help.
