    MT25418 ConnectX in Ethernet mode in ESXi 6.0?


      I have several MT25418 ("MT25418 [ConnectX VPI - 10GigE / IB DDR, PCIe 2.0 2.5GT/s]") adapters that I am trying to get operational in ESX 6.0 in 10G Ethernet mode.  Right now I'm trying to get them configured point-to-point but I'll probably be adding a 10G Ethernet switch at some future point.


      How do I make this card recognizable by ESXi 6.0?


      What is the combination of firmware/drivers that will get these adapters to be recognized in ESX and allow me to switch from IB mode to Ethernet mode?


      Here's what I have attempted so far:


      These HBAs were originally HP-branded HP Infiniband 4X DDR Connect-X PCI-e Dual Port HBA that I flashed to Mellanox-native v2.9.1 firmware on a Windows box.


      - Create a fresh install of ESX 6.0


      - From the VMware compatibility guide the MT25418 requires the "MLNX Native EN NIC driver", so I download and install the v offline bundle:


      esxcli software acceptance set --level=CommunitySupported

      esxcli software vib install -d /tmp/MEL-mlnx-




      After reboot I see:

      As you can see, the nmlx4_en Mellanox Ethernet module isn't loading. And I suspect it is due to the card defaulting to IB mode somehow somewhere.


      How do I make this card recognizable by ESXi 6.0?
