[Bug 1876021] [NEW] create multiple reserved_dhcp_port doesn't work as expected
Public bug reported:
I create a subnet 172.30.0.0/24, gateway 172.30.0.254, disabled dhcp, 3
dhcp servers per network.
In order not to occupy addresses like: 172.30.0.1, 172.30.0.2,
172.30.0.3, I want to specify dhcp port address use `reserved_dhcp_port`
feature:

a reserved_dhcp_port became active after enable dhcp, but the other two

Is it a normal action or undefined one? Can we improve it? Thanks in
