The solution to the problem with the new drivers turned out to be quite
trivial. Now, enabling the Trunk VF mode is done by adding a new parameter to
the network card driver registry parameter branch.

https://docs.nvidia.com/networking/display/winof2v25150020/ethernet+network#src-3576232145_EthernetNetwork-ConfiguringtheTrunkModeforVF

HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\*index*

Add parameter name 'TrunkModeForVfEnabled' type 'dword' value '1'.
An additional parameter is the range of vlans, parameter name
'TrunkModeForVfMaxVlans' type 'dword' (default value which is '1000') and is
range from '1' to '4094'.

Maybe this information will be useful to someone.
