sctp: count singleton chunks in assoc user stats
Singleton chunks (INIT, HEARTBEAT PMTU probes, and SHUTDOWN- COMPLETE) are not counted in SCTP_GET_ASOC_STATS "sas_octrlchunks" counter available to the assoc owner. These are all control chunks so they should be counted as such. Add counting of singleton chunks so they are properly accounted for. Fixes: 196d67593439 ("sctp: Add support to per-association statistics via a new SCTP_GET_ASSOC_STATS call") Signed-off-by: Jamie Bainbridge <jamie.bainbridge@gmail.com> Acked-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Link: https://lore.kernel.org/r/c9ba8785789880cf07923b8a5051e174442ea9ee.1649029663.git.jamie.bainbridge@gmail.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
