The current kernel does not provide any diagnostic tool, except
getsockopt(TCP_ULP), to know more about TCP sockets that have an upper
layer protocol (ULP) on top of them. This series extends the set of
information exported by INET_DIAG_INFO, to include data that are
specific to the ULP (and that might be meaningful for debug/testing
purposes).

Series applied, thanks Davide.
