Right: in the test

+ if ((dev->dev->caps.bmme_flags & MLX4_BMME_FLAG_LOCAL_INV) &&
+ (dev->dev->caps.bmme_flags & MLX4_BMME_FLAG_REMOTE_INV) &&
+ (dev->dev->caps.bmme_flags & MLX4_BMME_FLAG_FAST_REG_WR))
+ props->device_cap_flags |= IB_DEVICE_MEM_MGT_EXTENSIONS;

you will see that not all the bmme_flags required are set by FW 2.5.
