Yes, this is probably an intermediate step. I have asked Vijay to look
at the idea of creating a repo for these network services.
Unfortunately, there were a few lines of code in the telnetd that
seemed to be enabled only for the legacy stack, so it seems the
telnetd isn't totally stack independent. In case some minor adaptation
seems to be necessary based on the network stack, and we can't know
what that stack will be for sure at RTEMS build time since we
eliminated those configuration options. So, it doesn't make sense to
keep these network services in rtems.git, without having a network

I anticipate that we will attempt to migrate and merge the network
services, starting with telnetd, into a new repo that can be built
after the user selects their network stack. Our first priority is to
get things separated from rtems.git, and to get an lwip stack up in
parallel. Then, we would like to see how well the telnetd code base
can work with lwIP. Probably, we will get this done in the summer.

Other ideas are welcomed.
