[Zeek] "bro-cluster-in-a-box-setup" to "zeek-cluster-in-a-box-setup"?

[Justin Hayek]

You can absolutely do this. We are using af_packet and bonded interfaces throughout the majority of our deployments (approximately 1800 sensors).

We decided on af_packet as it was included in recent (at the time 2yrs ago) kernels. I can't speak to non-Debian based distro's, but we haven't seen any issues related to the use of af_packet.
