When possible, overlay2 is the recommended storage driver.
Supported backing filesystems: xfs with ftype=1, ext4 ( where /var/lib/docker/ is located )

https://hicu.be/macvlan-vs-ipvlan
- Ipvlan：All sub-interfaces share parent’s MAC | vs Macvlan
- Ipvlan L3 mode：Each sub-interface has to be configured with a different subnet
- Macvlan and ipvlan cannot be used on the same parent interface at the same time.
https://docs.docker.com/network/ipvlan/
- IPvlan L2 mode trunking is the same as Macvlan with regard to gateways and L2 path isolation.
--internal: ( off-o parent=)- if no
--gateway: gw for--subnet=192.168.1.0/24will be 192.168.1.1
