Docker 1.10 not assigning MAC provided by remote plugin it works for 1.11

Hi,

I am remote plugin which is used being used to create macvlan endpoint for the containers. 

I am trying to create MAC address from the plugin and pass it in Create Endpoint response. 

I can see the MAC address in docker inspect. However, if I exec into the container I see some random MAC address. 

Same thing works with docker 1.11.

Can someone tell what changed from 1.10 to 1.11
