Separate DHCP end address and subnet mask (vmnet)

[ktprograms]

In vmnet, you can specify the DHCP end address separately from the subnet mask, which allows the remaining addresses after the DHCP end to be statically assigned (I'm not sure if this actually works, but the documentation says it does). (The keys are end-address= and subnet-mask= in the QEMU vmnet options)

(To be clear, what I think would be good is having 3 separate options, Start Address, End Address, Subnet Mask)

The current setting is confusing, as you have to work out the subnet mask size yourself if you want to shrink the DHCP pool, and you also can't have a non-DHCP (static assignment) area.

This option is already available (in a slightly different form), in the QEMU backend, using the dhcpstart option.

We don’t use vmnet directly in AVF. It’s same with hypervisor.framework. AVF hides all those details from you. Can you check if such functionality exists for AVF?

Oh right, I forgot I only found out its not adjustable in AVF after writing most of this

This change should be used in the qemu arguments for vmnet (iirc its the useVmnet code path in the argument generation)

For avf it can't be helped (no control over IP ranges) afaik

Sorry for the confusion
