Hi,

Some fixes for taprio, mostly (2/3 and 3/3) related to the 'flags'
argument:

Patch 1/3: Reported by Po Liu, is more of a improvement of usability for
drivers implementing offloading features, now they can rely on the
value of dev->num_tc, instead of going through some hops to get this
value.

Patch 2/3: Changing the "flags" parameter during "runtime" was never
supposed to work, but if the user didn't set it at the beginning, we
were still allowing it.

Patch 3/3: Improves the code, so a similar situation fixed by 2/3 is
harder to happen again, and has the intended side effect that users do
not need to specify the "flags" argument when changing schedules when
some kind of offloading is enabled.


Cheers,
