libnetfilter_queue is a userspace library providing an API to packets that have been queued by the kernel packet filter. libnetfilter_queue library is is part of a system that deprecates the old ip_queue / libipq mechanism.
libnetfilter_queue has been previously known as libnfnetlink_queue.
Here are some key features of "libnetfilter_queue":
· receiving queued packets from the kernel nfnetlink_queue subsystem
· issuing verdicts and/or reinjecting altered packets to the kernel nfnetlink_queue subsystem
· a kernel that includes the nfnetlink_queue subsystem (i.e. 2.6.14 or later)
