Testing locally it works.

vm1 # ip route
default via 192.168.205.1 dev enp0s1 proto dhcp src 192.168.205.5 metric 100

vm2 # ip route
default via 192.168.205.1 dev enp0s1 proto dhcp src 192.168.205.6 metric 100

Create macvlan network.

vm1 # nerdctl network create mac0 -d macvlan --subnet=192.168.205.0/24 --ip-range=192.168.205.100/28

vm2 # nerdctl network create mac0 -d macvlan --subnet=192.168.205.0/24 --ip-range=192.168.205.200/28

Create container in macvlan network.

vm1 # nerdctl run -it --rm --net mac0 busybox sh
#  ip route
default via 192.168.205.1 dev eth0
192.168.205.0/24 dev eth0 scope link  src 192.168.205.100

vm2 # nerdctl run -it --rm --net mac0 busybox sh
#  ip route
default via 192.168.205.1 dev eth0
192.168.205.0/24 dev eth0 scope link  src 192.168.205.197

Test connectivity.

vm1: ping 192.168.205.197 -c 1
1 packets transmitted, 1 packets received, 0% packet loss

vm2:  ping 192.168.205.100 -c 1 
1 packets transmitted, 1 packets received, 0% packet loss

Thanks, could you update README.md and docs/cni.md ?

Would be nice if we can have CI too
