New Revision: 282300
URL: https://svnweb.freebsd.org/changeset/base/282300
Log:
Add a state transition call to show that we have entered TIME_WAIT.
Although this is not important to the rest of the TCP processing
it is a conveneint way to make the DTrace state-transition probe
catch this important state change.
