Macvlan bridge STILL doesn't work for Wifi

Got my new Raspberry Pi 4 and I installed the 64-bit Raspberry Pi OS and was playing with Docker.

I was having problems getting macvlan working. I struggled. I reinstalled. Nothing seemed to work. On a whim I looked to see if this might just be a problem with me experimenting with bare bones installs so googled a couple things and found the Blog from Barry Kauler titled Macvlan bridge does not work for wifi. Sure enough. If you try and share the connection with wlan0 instead of eth0 it just doesn't work.

So I plugged it in and forced it to use eth0 and sure enough now everything works as expected. 

Thanks Barry!
