Hello again

I have a use case where I am installing an OS via the PXE server and I need the DHCP server to respond to a previously known PXE client.

The workflow is as follows currently:

system requests IP as PXE client (accepted)
select OS install from PXE menu
OS installer needs DHCP address to communicate but is rejected because it is not a PXE client any more (rejected)

Proposed change:

move to MAC based leases, if a specific MAC makes multiple DHCP requests it will always receive the same
- right now only IP and timeout are captured. Proposal is to add MAC as primary key and keep both IP and timeout as children of the MAC key.
add flag to accept previous PXE clients so that my use case will be satisfied

I have PRs ready but want to confirm this flow is proper before I submit.

Thanks
