To be able to use netdevsim for tc-testing with an offloaded tc-taprio schedule, it needs to report a PTP clock (which it now does), and to accept ndo_setup_tc(TC_SETUP_QDISC_TAPRIO) calls. Since netdevsim has no packet I/O, this doesn't do anything intelligent, it only allows taprio offload code paths to go through some level of automated testing.
