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