Subject: [RFC net-next 0/5] Add ETS and TBF Qdisc offload for Airoha EN7581 SoC

Introduce support for ETS and TBF qdisc offload available in the Airoha
EN7581 ethernet controller.
Some DSA hw switches do not support Qdisc offloading or the mac chip
has more fine grained QoS capabilities with respect to the hw switch
(e.g. Airoha EN7581 mac chip has more hw QoS and buffering capabilities
with respect to the mt7530 switch). 
Introduce ndo_setup_tc_conduit callback in order to allow tc to offload
Qdisc policies for the specified DSA user port configuring the hw switch
cpu port (mac chip).

Lorenzo Bianconi (5):
  net: airoha: Enable Tx drop capability for each Tx DMA ring
  net: airoha: Introduce ndo_select_queue callback
  net: dsa: Introduce ndo_setup_tc_conduit callback
  net: airoha: Add sched ETS offload support
  net: airoha: Add sched TBF offload support
