This directory is not specific to black box logging, but the userland tool tcplog_dumper. Not sure if it should be mentioned here.

Maybe: Enable continual logging for all TCP connections:

You might want to add a note that using a config with

net.inet.tcp.bb.log_auto_mode=1

keeps up to the last net.inet.tcp.bb.log_session_limit entries stored at the TCP endpoint. Nothing is dumped to disk.
So when debugging TCP related panics, this is a good way to capture information about the panic.

You also might want to cross reference to tcpsso.8. The man page shows an example how to enable continual logging for a specific TCP connection via the command line.

It was written by Jonathan Looney (jtl) and Randall Stewart (rrs), not by me.

You might also add a reference to Adventures in TCP/IP: TCP Black Box Logging.

I mentioned it in the CONFIGURATION section.

It is fixed. The comment was about the code, not the article.
