Subject: [PATCH net-next v4 0/6] tsnep: multi queue support and some other improvements

Add support for additional TX/RX queues along with RX flow classification
support.

Binding is extended to allow additional interrupts for additional TX/RX
queues. Also dma-coherent is allowed as minor improvement.

RX path optimisation is done by using page pool as preparations for future
XDP support.

v4:
- rework dma-coherent commit message (Krzysztof Kozlowski)
- fixed order of interrupt-names in binding (Krzysztof Kozlowski)
- add line break between examples in binding (Krzysztof Kozlowski)
- add RX_CLS_LOC_ANY support to RX flow classification

v3:
- now with changes in cover letter

v2:
- use netdev_name() (Jakub Kicinski)
- use ENOENT if RX flow rule is not found (Jakub Kicinski)
- eliminate return code of tsnep_add_rule() (Jakub Kicinski)
- remove commit with lazy refill due to depletion problem (Jakub Kicinski)

Gerhard Engleder (6):
  dt-bindings: net: tsnep: Allow dma-coherent
  dt-bindings: net: tsnep: Allow additional interrupts
  tsnep: Move interrupt from device to queue
  tsnep: Support multiple TX/RX queue pairs
  tsnep: Add EtherType RX flow classification support
  tsnep: Use page pool for RX
