      SCTP transport for knet is now deprecated in Corosync::
      Previously, the `knet` transport protocol in Corosync allowed the selection of Stream Control Transmission Protocol (SCTP), although this specific transport was not officially supported in RHEL.
      +
      With this update, using SCTP for `knet` transport is officially deprecated. The option to use SCTP might be removed in a future release.
      +
      As a result, users are advised to transition to supported transport protocols. The `pcs cluster setup`, `pcs cluster link add`, and `pcs cluster link update` commands now display a warning if SCTP is specified for `knet` transport.
