Hallo Vijay,
I still have to ask a question ;-)

When building EPICS, we distinguish legacy stack or libbsd with the help of
the target.cfg file. (e.g. powerpc-rtems6/beatnik/make/target.cfg).

Earlier in it was 
RTEMS_HAS_NETWORKING = yes (for legacy stack) and no (for new bsd stack).

Now  this flag will no be set with the waf build in your extra net-legacy repo.

How should we now find out if the target was built with legacyStack or with libbsd?

Danke Heinz
