Ok Fabio, I did a lot of research yesterday, I installed like 4 Vms on ESXi 6.0 and 4 VMs on Vmware Workstation Pro 16. Here is the info about. I tried the models ds3615, ds3617, ds3622, dva1622, dva3221.
All the models with the 10GB virtual network VMXNET3 work with perfection and have the MTU9000 option open on all the DSM 7.x.
The ds3622xs and the dva1622 with intel E1000 and E1000E on DSM 7.X doesn't give me the option to change from MTU1500 to more.
I don't know if the driver's version on the loader scripts is different for each model, or they are the same and use the same source for every model.
If you can compile a new version of e1000 and e1000e for the DS3622 and the DVA1622, then I can test them on ESXi, VMware Workstation Pro and BareMetal. They all have the old intel network card.
PS: I couldn't add the GitHub URL with e1000e on the loader, I tried to copy the whole URL and the error was: file format no recognized
