That's not the issue here.
The issue is that a server is receiving two copies of the DISCOVER a few
milliseconds apart with different giaddr, but only responding to one.
The "min-secs" setting could, in theory, cause it to ignore *both*. But:
a. We have no min-secs on the affected server, and
b. secs==0 in the affected packets
