Description

Considering that an alert could be discarded from the packet queue due to queue size limitations, we must consider how signatures with the `drop` action are still taken into account, even if the respective alert is dropped.

I guess... thought must also be given with regards to how do we indicate what is going on with said traffic, even if the alert isn't kept. Debug log? Specific stats counter?
