goldsimon	f4036e8352	Another fix for bug #20021: by not returning an error if tcp_output fails in tcp_close, the code in do_close_internal gets simpler (tcp_output is called again later from tcp timers).	2007-07-25 19:24:27 +00:00

fbernon	5c65d4733b	Keepalive values can be configured at run time with LWIP_TCP_KEEPALIVE, but don't change this unless you know what you're doing (default are RFC1122 compliant). Note that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds. ... Old TCP_KEEPALIVE can always be used, and its only difference with TCP_KEEPIDLE is this last use seconds and not milliseconds with setsockopt.

kieranm	751557bcbf	16th October 2004 - Kieran Mansley - kjm25@cam.ac.uk ... - Add code to tcp_recved() to send an ACK (window update) immediately, even if one is already pending, if the rcv_wnd is above a threshold (currently TCP_WND/2) - This avoids waiting for a timer to expire to send a delayed ACK in order to open the window if the stack is only receiving data.	2004-10-16 12:57:52 +00:00

davidhaas	32d9f25a6f	Fixed up and made work a PBUF_REF type. Most of the code uses this now ... instead of PBUF_ROM. This addition allows support of copy-on-demand where the lower layers can call pbuf_unref() which tests for any PBUF_REF buffers and replaces them with PBUF_POOL buffers. This is now used everywhere. pbuf_unref() is called in ARP queueing and in the coldfire driver, which puts frames on a DMA queue and frees them later. Along with this change pbuf_free() now goes through the entire chain of buffers and tests all the ref counters, not just the first one. Generally now pbuf_ref_chain() should be called and not pbuf_ref(). This change was made because it is possible for the head of the pbuf chain to have a different count than the payload pbuf which might have been passed by the application.	2003-03-19 22:14:49 +00:00
