CVS commit: syssrc/sys/netinet

[Jason R Thorpe <thorpej%netbsd.org@localhost>]

Module Name:    syssrc
Committed By:   thorpej
Date:           Mon Sep 10 15:23:12 UTC 2001

Modified Files:
        syssrc/sys/netinet: tcp_input.c tcp_output.c tcp_timer.c tcp_var.h

Log Message:
Change the way receive idle time and round trip time are measured.
Instead of incrementing t_idle and t_rtt in tcp_slowtimo(), we now
take a timstamp (via tcp_now) and use subtraction to compute the
delta when we actually need it (using unsigned arithmetic so that
tcp_now wrapping is handled correctly).

Based on similar changes in FreeBSD.
