Subject: [PATCH 2/4] net: airoha: Introduce ndo_select_queue callback
|
|
|
|
Airoha EN7581 SoC supports 32 Tx DMA rings used to feed packets to QoS
|
|
channels. Each channels supports 8 QoS queues where the user can apply
|
|
QoS scheduling policies. In a similar way, the user can configure hw
|
|
rate shaping for each QoS channel.
|
|
Introduce ndo_select_queue callback in order to select the tx queue
|
|
based on QoS channel and QoS queue. In particular, for dsa device select
|
|
QoS channel according to the dsa user port index, rely on port id
|
|
otherwise. Select QoS queue based on the skb priority.
