Could not join netdev: No space left on device - Mellanox ConnectX-3 Pro EN / HP 544+QSFP 764284-B2

I am trying to run 200 vlan on one port and I am getting errors. I updated the driver to the latest 4.9 LTS and firmware too, but it didn't help. I noticed that the maximum can be only 126 vlan, but not more. If I put a network adapter with an Intel chip, then everything is fine. Tell me what is the problem?

 

Ubuntu Server 18.04 LTS
