What is cufwAaicInjDropCount?

This Counter64, in Packet, counts packets that Snort added into the traffic stream but that subsequently got dropped. An admin uses this to see how many of Snort's own injected packets, such as reset packets meant to tear down a connection, failed to actually make it through. A nonzero and growing value here alongside expected connection terminations would suggest some of Snort's teardown packets aren't successfully reaching their destination.
