** Description changed:
+ [Impact]
+
+ * suspend/resume (which involves disconnection of network devices)
+ leads to dnsmasq failures.
+
+ [Test Case]
+
+ * suspend/resume on 16.04 or 16.10 when using dnsmasq, and see failures
+ upon resume.
+
+ [Regression Potential]
+
+ * The fix was NMU'd in Debian in the version immediately after 16.10's.
+ I believe the regression potential is very low as this is a clear bug-
+ fix from upstream.

Failure is caused by ENODEV return for all dns queries like:
sendto(11, "\232\325\1\0\0\1\0\0\0\0\0\0\4mail\6google\3com\0\0\1\0"..., 33,
0, {sa_family=AF_INET, sin_port=htons(53),
sin_addr=inet_addr("62.241.198.245")}, 16) = -1 ENODEV (No such device)

I didn't yet test if applying that patch to ubuntu package works. I will
try the patch in a few hours.
