I am trying to move wlan0 interface from host to container with the below configuration,

lxc.network.type = phys
lxc.network.link = wlan0
lxc.network.hwaddr = ab:cd:ef:gh:ij
lxc.network.flags = up

Which works perfectly with my external TP-Link wifi dongle and I can see wlan0 interface available inside the container by running ifconfig

But I do also have an integrated ALPS wifi chip for which the same container configuration won't work and fails with the below error.

lxc-start 20170704134254.641 ERROR    lxc_conf - conf.c:lxc_assign_network:3102 - failed to move 'wlan0' to the container : Operation not permitted

I have also found a thread where it says till sysfs virtualization is not finalized the kernel will have this limitation.

If that's the case, how did it worked for my external wifi dongle?

Or is it something else which I'm missing?
