We need to maintain our current functionality and I am prepared to 
bridge but not abandon. The libbsd stack has made progress but does not 
support as much as the old stack does. Until it does I feel we need to 
keep the old stack going and to support it.

To me this means adding headers to newlib requires the in-tree stack and 
libbsd work with out impacting users and existing applications.

If I understand what is bring proposed any suitable networking software 
should be able to be built against just the compiler, newlib etc and it 
does not need a built and installed RTEMS with a specific networking 
implementation. This means networking could become a link time setting. 
An interesting challenge.

Sebastian, I know you have talked about libressl, but it is still not 
clear to me why doing this is needed. Do you have a specific use case?
