3) wait for UEFI and driver updates for the INTEL 219-LM integrated network adapter from DELL, maybe someday they will fix their error.
2) install Linux for example UBUNTU (20.4 LTS). And so there are 3 options: 1) buy a pci-e network adapter from another manufacturer with support for 802.1q (not INTEL). Because of this approach to the buyer, I will never buy DELL equipment again. And to try to solve the error that I think is in UEFI, they offer me to pay money. 802.1q functionality is officially announced and should work in the system. Then they wrote: "since you do not have a hardware problem with the network adapter, then you need to contact extended technical support, but you will have to pay for their help"! O_O I'm a little surprised here, of course. They sent links to their drivers, but there is no sense from them. One message from INTEL: "For an embedded network card, the manufacturer may have made changes to the controller to accommodate their system, and these changes are beyond our support." DELL claims to have made no changes. INTEL technical support sent different instructions, all without success, the driver from their website was not installed. All last week I talked with INTEL and DELL technical support.
