You should probably split that patch in a minimum of two, or more
different parts.
Two parts:
- add TX multiqueue support
- add RX multiqueue support
More parts:
- prepare for TX multiqueue (introduce queue structure, definitions)
- transition TX path to use queue 0
- add support for the two other TX queues
- prepare for RX multiqueue (introduce queue structure, definitions)
- prepare for multiqueue, hardcode RX path to use queue 0
- add support for the two other RX queues
The number of changes are extremely hard to review...
