This chapter describes the devctl() commands that apply to the Precision Time Protocol. If you specify the -k option, ptpd and ptpd-avb register /dev/ptpd (DEFAULT_PTPD_PATH, defined in <dcmd_ptpd.h>) in the path namespace; use these commands with a file descriptor from opening this path.

Note: Some of these commands are supported only by ptpd-avb; see the individual entries.
