Tried it, after boot, the adapter doesn't get any ip.
I assume that it might be related to the fact that when dhcpcd is executed, the device doesn't exists, hence the hotplug.
I tried to look for config examples for /etc/dhcpcd.conf that supports dhcp but all I find are static ips.
Any idea where I can find dhcp config for /etc/dhcpcd.conf?

Thanks,
