Nah, the wireless connection stays up. It's just the DHCP renewal requests
that suddenly happen again and again.

Perhaps it has something to do with the DHCP request being broadcast, and
thus received on BOTH interfaces, and dhcpcd not liking that the first reply
is on eth0 (simply because wired ethernet is faster than wifi)? But if so,
then why does the original request work, and only the renews fail?

For now, my workaround is to set the lease period for this address to a
ridiculously high amount. Unfortunately, that's not a good workaround, if I
ever take the laptop roaming into somewhere which uses the same private IP
range.
