Author: jhb Date: Tue Dec 22 15:47:40 2009 New Revision: 200847 URL: http://svn.freebsd.org/changeset/base/200847 Log: - Rename the __tcpi_(snd|rcv)_mss fields of the tcp_info structure to remove the leading underscores since they are now implemented. - Implement the tcpi_rto and tcpi_last_data_recv fields in the tcp_info structure.
