ConnectX3 with MC2609130-001 cable (40GbE to 4x10GbE QSFP to 4xSFP+) in VMWARE only "port 1" is working (10GB)

I have a ConnectX3 card in ESXI 6.5 connected with the Mellanox MC2609130-001 Passive Copper Hybrid Cable Ethernet 40GbE to 4x10GbE QSFP to 4xSFP+ to an Alcatel Lucent 6900 switch. Only port 1 with 10 GB get into service. If I use a 40GB to 410GB cable to connect one Alcatel 40GB port to 410 GB Alcatel ports it works. I had to set the 40GB port on Alcatel to “split mode”. If I connect the ConnectX3 card with a 40GB cable to a 40GB port at Alcatel it works too.

Do I need to configure the ConnectX3 card to a kind of “split mode” in VMWare to have 4*10 GB links running as I did on the Alcatel switch?
