Hi,
vpp/flow_cli.c at master · FDio/vpp · GitHub
<https://github.com/FDio/vpp/blob/master/src/vnet/flow/flow_cli.c>
contains some useful information to add a flow to redirect to queue X
(check out test_flow() function's redirect_to_queue option, or
vl_api_flow_enable_t_handler if you are using API).
After a flow is configured you may enable the flow to an interface. If
the interface is managed by DPDK the vpp flow will be translated into
DPDK rte_flow and configure the NIC HW. Please note not all NIC HW
supports the flow configuration you might need.
However you still have to tweak the rest of your flows to not touch queue 0.
Regards,
Fan

Hi,
I am setting num-rx-queues for a dpdk dev in vpp startup config to 4.
This enables RSS and distribute packets coming on this interface
between these 4 queues.
I would like to configure RTE flow and redirect certain packets to
queue 0. When this is done, I don't want other packets to use queue 0
due to RSS.
Is there a way to disable RSS on set of rx-queues?
