There's a weird corner case in LwIP where, if the DHCP client is unable to get a response from a DHCP server after 256 tries, the DHCP retry counter (which is a u8_t) will roll over to zero, and the DHCP timout will stop invoking dhcp_timeout(). This is in a configuration where DHCP is enabled but AUTOIP is not.
