Hi,

ST micro has an example on how to use it. Check their latest examples for 
STM32F4

Hope that helped,
Noam.

When I did it, I basically polled for
    netif.dhcp->state == DHCP_BOUND
and read
        ipaddr = netif.ip_addr;
        netmask = netif.netmask;
        gw = netif.gw;

but now I realize the dhcp code calls netif_set_up() when it reaches
that state, which also calls NETIF_STATUS_CALLBACK if
LWIP_NETIF_STATUS_CALLBACK is defined.

Now, I've been calling netif_set_up() before dhcp_start() cause I though
the ifc needed to be somehow "up" before UDP/IP would be sent through
it... looks like I was wrong and that was not necessary, or worse, not
correct.
