On ADI website and in some documents I read
Lightweight TCP/IP (lwIP) is a widely accepted TCP/IP stack for embedded platforms ...
This is a port of the lwIP TCP/IP stack to the Analog Devices ADSP-BF60x,ADSP-BF52x, ...
But I can't find any information on which version of lwIP stack is included in Lightweight TCP/IP (lwIP) stack add-in.
Latest stable version of lwIP is 1.4.1 (December 2012) but it seems that in lwIP add-in 1.0.1 there is an older version (looking at CHANGELOG file and source files)
Could you clarify, please?
