Symptoms:
	PHNE_25245:
	Port HP-UX patch PHNE_13413 to VVOS

	Based on HP-UX patch PHNE_13413:
	The following symptoms correspond to the descriptions in
	the defect descriptions field for PHNE_13413:
	1. Slow throughput downloading continuous large amounts
	   of data over telnet connection.

	Based on HP-UX patch PHNE_9122:
	The following symptoms correspond to the descriptions in
	the defect descriptions field for PHNE_9122:
	1. The kernel portion of the Telnet server drops data
	   on a connection while attempting to receive data from
	   the Telnet client associated with that connection.

Defect Description:
	PHNE_25245:
	Port HP-UX patch PHNE_13413 to VVOS

	Based on HP-UX patch PHNE_13413:
	The following defect descriptions are for PHNE_13413:
	1. Currently in output, kernel telnet implements a
	   delay which forces small amounts of data to coalesce
	   before putting them into a packet, since sending too
	   many small packets quickly may overload a system.
	   This delay is causing slow throughput for large
	   amounts of data output.  This patch allows use of
	   OUT_NO_DELAY option from telnetd to remove the delay
	   in kernel telnet during output.
	   ** For 10.30 and later releases, the implementation
	   of telnet is changed so that throughput is increased,
	   so the telnetd option will no longer will needed and
	   will not be valid.**

	Based on HP-UX patch PHNE_9122:
	The following defect descriptions are for PHNE_9122:
	1. The problem is that an instance of nvs_input and an
	   instance of tcp_input are executing at the same time
	   and nvs_input is using a socket buffer as
	   tcp_input is modifying that socket buffer.  This
	   causes a situation in which nvs_input attempts socket
	   buffer data drops (sbdrop) using stale socket buffer
	   data.
