====================
net: ipconfig: improve DHCP timeout handling

this series teaches the ipconfig code to handle a DHCP reply on eth0 even if a
request on eth1 was already sent out.
This is a follow fix to 52bcefa7c392 ("ipconfig: handle case of delayed DHCP
server") that dropped a late reply.

This makes it possible at all to work with slow DHCP servers at all in some
configurations and improves boot speed in general.

The first patch is not really necessary, it only helps decoding debug messages
when there is more than one device.
