Follow-up Comment #1:
I think you mixed up the up/down-callback with the link-callback: the
up/down-callback notifies the application of the IP status (i.e. valid IP
address assigned or not), while the link-callback is mainly used internally to
the stack and notifies about changes to the hardware link (i.e. cable
pulled/plugged).
As such, triggering the link-callback from dhcp_bind() (when an IP address is
assigned) is not intended behaviour. The link-callback is only triggered when
your netif driver detects a link change and calls netif_set_link_up/down().
This has to be implemented in your driver. If it's not, the link status is
always detected as up.
