Description
I'm having a problem with trying to set mac_address when a container is part of more than one network. I first reported this here: https://github.com/docker/compose/issues/5261 but am wondering if this might be a better forum.
Basically, the provided mac_address only gets used on one network. Other networks that get set up use some generated mac_address.
This is a big problem for me because I need to use a fixed mac_address for a DHCP reservation. Right now I can only do that for a container that is only on one network.

Research direction
Start by reproducing the reported case: place one container on multiple networks and configure a fixed mac_address, then trace how the address is applied during network setup. Done means the configured MAC is used on every attached network, with regression coverage for the multi-network case.
