Hello netsniff-ng team!

We recently discovered an issue with the default scatter-gather I/O:
https://groups.google.com/d/topic/security-onion-testing/OuD7xt7nQuI/discussion

Questions:

- Is it expected behavior for the default scatter-gather mode to wait
several minutes before writing packets to disk if on a low-traffic
network?

- We're working around this by setting the "-c" option to disable
scatter-gather mode when running on low-traffic networks.  Is this the
best workaround?

- Is scatter-gather mode dependent on scatter-gather being enabled on
the NIC?  We currently disable NIC offloading features like this:
post-up for i in rx tx sg tso ufo gso gro lro; do ethtool -K $IFACE $i off; done

Thanks!
