Subject: [PATCH net v2 0/3] taprio: Some fixes

Hi,

Changes from v1:
  - Fixed ignoring the 'flags' argument when adding a new
    instance (Vladimir Oltean);
  - Changed the order of commits;

Updated cover letter:

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: Use 'q->flags' as the source of truth for the offloading
flags.

Patch 3/3: Fixes the issue that changing the flags during runtime was
still allowed (with bad results). The solution was to initialize
'q->flags' with an invalid value.

Cheers,
--
Vinicius
