  Modified files:        (Branch: RELENG_5)
    sys/netinet          tcp_output.c tcp_subr.c tcp_var.h 
  Log:
  MFC:
    tcp_output.c rev 1.109, tcp_subr.c rev 1.222, tcp_var.h rev 1.120.
  
    Ignore ICMP Source Quench messages for TCP sessions.  Source Quench is
    ineffective, depreciated and can be abused to degrade the performance
    of active TCP sessions if spoofed.
  
    Replace a bogus call to tcp_quench() in tcp_output() with the direct
    equivalent tcpcb variable assignment.
