+Subject: [PATCH] ptp4l: Remove bogus command line option.
+
+Commit c8107c8d ("config: Add a configuration option for TC mode.")
+added a new TC mode.  An early version of the patch series included a
+new '-t' command line option, but this was dropped considering the
+fact that long options are always available.  IOW the TC user can
+simply add '--clock_type=P2P_TC' to the command line, making the
+single dash option redundant.
+
+This patch fixes the misleading usage message by removing the
+non-existing option.
