[net-next,v3,0/6] tsnep: multi queue support and some other improvements

Message

Gerhard Engleder Sept. 23, 2022, 8:29 p.m. UTC

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.

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)
