Macvlan/ipvlan sharing subnet with host #5026

Description

With docker you can create a macvlan (or ipvlan) that uses the same subnet as the parent interface. With nerdctl this results in:

FATA[0000] subnet 192.168.100.0/24 overlaps with other one on this address space

Steps to reproduce the issue

1. Figure out what IP subnet your host network interface is on (e.g. with ip addr or ifconfig) and use interface and subnet that in the commands below:
2. nerdctl network create mac0 --driver macvlan -opt=parent=enp0s31f6 --subnet=192.168.100.0/24 --gateway=192.168.100.1
3. Compare with the same with docker, which is successful

Describe the results you received and expected

I would expect to be able to have containers that are on the same subnet as the host is on, as is possible with docker.
