esxi7.0 NVME-OF,after install the driver, cannot find the nvme adapter.

Hi All:

     1,  download the Emulex LPe32002-AP driver from here : https://my.vmware.com/group/vmware/details?downloadGroup=DT-ESXI_70-BROADCOM-BRCMNVMEFC-1262284&productId=974&download=t… 

2, install the driver : "esxcli software vib install -v /tmp/vib20/brcmnvmefc/EMU_bootbank_brcmnvmefc_12.6.228.4-1OEM.700.1.0.15525992.vib"

3, set  the driver parameter lpfc_enable_fc4_type=3 ,  " esxcli system module parameters set -p lpfc_enable_fc4_type=3 -m lpfc"

4, reboot

after the system reboot ok , cannot find the nvme adapter ."esxcli nvme adapter list" return null.

which step is wrong ? Could you please give me some suggestion ?

Thanks.
