/*
* 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.
