I wait to call dhcp_start until I see that I have a link established.

... and as a reminder to those who don't know:
- netif_set_link_callback() is used to set a callback per netif to get informed when the lwIP-internal link state changes.
- netif_set_link_up()/netif_set_link_down() is used by netif drivers to report the link status to lwIP (e.g. after getting an interrupt from the PHY)
