We are attempting to use TCP to connect to a remote target, however, we noticed that our
posix socket layer is not being loaded. When spdk_sock_connect is called, there does not
seem to be any items in g_net_impls.
How does g_net_impls get populated on the client side? We've looked at the
hello_sock sample and there doesn't seem to be anything tricky happening before
spdk_sock_connect is called.
