Chen,
Are you using the following frame work for you development?
Release Notes - AVR32 UC3 Software Framework
--------------------------------------------
Release version: 1.4.0
Release date: 2008-12-09
If this looks familiar, your framework
is using the 1.3.0 stack. Can we see your opt.h file found in ‘\src\include\lwip’.
This will clear up the confusion as to which macros are impacting your stack
configuration.

The debug macros have been renamed to include the LWIP_ prefix back in 1.3.0,
so the lwipopts.h you are using has been designed for 1.2.0, and that's a
really long time ago.

That's true: the socket- and netconn-API both don't use netbufs for sending TCP
data.
Other than that, you could check which macros that are defined in opt.h are not
defined in your lwipopts.h. There might be some new defines which set to low
values which you didn't override?
BTW, what version of lwIP are you using? Because of the splitted thread, that's
not really clear to me right now.
