Maybe I don't understand what is special about this case, but to me it feels odd that applications would need to be configured to use the right PHC. Applications that automatically enable HW timestamping on all interfaces would break, right? Or does the ioctl return no index so the interface would normally be ignored? Any chance this could be addressed at the kernel, driver, and/or device tree? -- Miroslav Lichvar _______________________________________________ Linuxptp-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linuxptp-devel
