Documented steps
Recognize the Linux kernel restriction: containers attached to a macvlan network cannot communicate with the Docker host directly.
Option A: attach the container to a bridge network in addition to macvlan, e.g. docker run --network=<macvlan-net> ... then docker network connect <bridge-net> <container>, so the host is reachable over the bridge.
Option B: create a macvlan interface on the host using the same parent interface and assign it an IP inside the Docker network's subnet so the host has a presence on the macvlan segment.
Prefer bridge or overlay networking when host-to-container communication matters; reserve macvlan for direct LAN-style connectivity.

Known gotchas
There is no flag or setting that lifts the kernel restriction - the bridge-attach or host-interface workarounds are the only supported paths.
This restriction affects all macvlan networks regardless of mode.
