This subsystem is superseded by modern debugging facilities, e.g. DTrace probes and TCP black box logging. We intentionally leave SO_DEBUG in place, as many utilities may set it on a socket. Also the tcp::debug DTrace probes look at this flag on a socket. Reviewed by: gnn, tuexen Discussed with: rscheff, rrs, jtl Differential revision: https://reviews.freebsd.org/D37694

/*

* These constants originate from the 4.4BSD sys/protosw.h. They lost
|
|
* their initial purpose in 2c37256e5a59, when single pr_usrreq method
|
|
* was split into multiple methods. However, they were used by TCPDEBUG,
|
|
* a feature barely used, but it kept them in the tree for many years.
|
|
* In 5d06879adb95 DTrace probes started to use them. Note that they
|
|
* are not documented in dtrace_tcp(4), so they are likely to be
|
|
* eventually renamed to something better and extended/trimmed.
