Ubuntu 16.04 LTS - LXD export of bcm wifi iface fails

[epoch1970]

FYI, exporting the physical wifi interface of Pi 3 to an LXD container fails.
I'm playing with LXD on a Pi 3 with an ubuntu distro: Ubuntu 16.04 LTS (GNU/Linux 4.4.0-1016-raspi2 armv7l)

I can't get the Broadcom wifi interface to emerge into a container, but I was surprised it would work with an Edimax EW-7811Un USB card:

Code: Select all

root@berck:~# iw phy phy0 set netns 16099
command failed: Operation not supported (-95)
root@berck:~# iw phy phy1 set netns 16099
root@berck:~# lxc exec again bash

root@again:~# ifconfig -a
[SNIP]

In addition the "iw phy" rigmarole is sub-optimal; You have to run it from the host, once the guest has started... I would love if in the future I could simply configure once and for all my container with something like:
"lxc config device add container wlan0 nic nictype=physical parent=wlan0" or
"lxc config device add container phy0 nic nictype=physical parent=phy0"

Thanks!
