Module Name:    syssrc

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

Log Message:
Use callouts for TCP timers, rather than traversing the list of
all open TCP connections in tcp_slowtimo() (which is called 2x
per second).  It's fairly rare for TCP timers to actually fire,
so saving this list traversal is good, especially if you want
to scale to thousands of open connections.
