Vinicius Costa Gomes 602fae856d taprio: Add support for changing schedules ... This allows for a new schedule to be specified during runtime, without removing the current one. For that, the semantics of the 'tc qdisc change' operation in the context of taprio is that if "change" is called and there is a running schedule, a new schedule is created and the base-time (let's call it X) of this new schedule is used so at instant X, it becomes the "current" schedule. So, in short, "change" doesn't change the current schedule, it creates a new one and sets it up to it becomes the current one at some point. In IEEE 802.1Q terms, it means that we have support for the "Oper" (current and read-only) and "Admin" (future and mutable) schedules. Example of creating the first schedule, then adding a new one: (1) tc qdisc add dev IFACE parent root handle 100 taprio \ num_tc 1 \ map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 \ sched-entry S 0x1 1000000 \ sched-entry S 0x0 2000000 \ sched-entry S 0x1 3000000 \ sched-entry S 0x0 4000000 \ base-time 100000000 \ clockid CLOCK_TAI (2) tc qdisc change dev IFACE parent root handle 100 taprio \ base-time 7500000000000 \ sched-entry S 0x0 5000000 \ sched-entry S 0x1 5000000 \ It was necessary to fix a bug, so the clockid doesn't need to be specified when changing the schedule. Most of the changes are related to make it easier to reuse the same function for printing the "admin" and "oper" schedules.
