[ovs-discuss] [dpdk-dev] Does ovs-dpdk support QoS on dpdkvhostuser port and other port?

[Sam]

Thank you,

I found normal ovs support this:

set port eth0 qos=@newqos -- \
> --id=@newqos create qos type=linux-htb \
> other-config:max-rate=1000000000 \
> queues:123=@vif10queue \
> queues:234=@vif20queue -- \
> --id=@vif10queue create queue other-config:max-rate=10000000 -- \
> --id=@vif20queue create queue other-config:max-rate=20000000


so I want to know whether dpdkport support command like this:

set port dpdkport qos=@newqos -- \
> --id=@newqos create qos type=dpdk-qos-xxx-type \
> other-config:max-rate=1000000000 \
> queues:123=@vif10queue \
> queues:234=@vif20queue -- \
> --id=@vif10queue create queue other-config:max-rate=10000000 -- \
> --id=@vif20queue create queue other-config:max-rate=20000000


If this support, what's 'dpdk-qos-xxx-type' is?

Thank you~
