Well, I don't know how your DHCP client works (or how ifplugd is
supposed to work for that matter), so that may or may not be normal. If
the DHCP client is clever enough, it will check the operstate setting
(IFLA_OPERSTATE) before starting to actually request IP configuration.
Alternatively, ifplugd should do this. wpa_supplicant will set the
operstate to IF_OPER_UP once the interface is ready for normal data
traffic (including DHCP).
