docker network macvlan 驱动程序不支持 driver_opts：MTU

Question

According to https://docs.docker.com/v17.09/engine/userguide/networking/work-with-networks/#connect-containers

driver_opts are:

com.docker.network.bridge.name  -   bridge name to be used when creating the Linux bridge
com.docker.network.bridge.enable_ip_masquerade  --ip-masq   Enable IP masquerading
com.docker.network.bridge.enable_icc    --icc   Enable or disable inter container connectivity
com.docker.network.bridge.host_binding_ipv4 --ip    Default IP when binding container ports
com.docker.network.driver.mtu   --mtu   Set the containers network MTU

I've changed the MTU of bridge driver by creating a network with a value to --mtu which works.

But the same option, --mtu, does not work if I change the driver to macvlan

Are the driver_opts different for macvlan? If so, what is its options to change MTU for macvlan driver for docker network create ?

这是由于 libnetwork 中的一个长期存在的错误： https ://github.com/moby/libnetwork/issues/2274
