Cannot install driver for MT27500 on CentOS 7.2

When I attempt to install the driver for this card, I get the following error:

Uninstalling the previous version of mlnx-en

Failed to uninstall the previous installation

Collecting debug info…

See /tmp/mlnx-en-4.1-

lspci output shows the card:

a0:00.0 Network controller: Mellanox Technologies MT27500 Family [ConnectX-3] (rev ff)

Also if I try to update the firmware, I get the following error:

Infiniband : card detection : DETECTED FDR Mellanox

Infiniband : card position : DETECTED @ a0:00.0

Infiniband : mlx FDR detection : PASSED

Infiniband : mlx FDR revision : ABORTING! (/usr/bin/mlxburn is missing)

FDR Infiniband : Firmware expected 2.32.5100 : Can’t Detect current firmware

Infiniband : mlx FDR FW flash file : Can’t find:

Firmware update not possible.

/usr/bin/mlxburn does exist though
