Hello maintainers,
I am currently facing issues when creating RSS flows using testpmd.
When using the following flow on an intel NIC, it works as expected,
using the reta table to redirect ipv4-udp packets to the correct queue.
flow create 0 ingress pattern eth / ipv4 / udp / end actions rss types
ipv4-udp end queues end func toeplitz / end
However when executing the same command on a Mellanox NIC, the following
error occurs.
Caught PMD error type 15 (action configuration): No queues
configured: Invalid argument
This error can be resolved by manually specifying the queues used:
flow create 0 ingress pattern eth / ipv4 / udp / end actions rss
types ipv4-udp end queues 0 1 2 3 4 5 6 7 8 end func toeplitz / end
However the packets are not placed into their expected queues using the
reta table.
When looking through the Generic flow API guide under RSS
(https://doc.dpdk.org/guides/prog_guide/rte_flow.html), the attribute
queues does not exist.
From my understanding this seems to be a mistake, as the attribute
"queue" does exist with the definition "queue indices to use"
However when attempting to use this attribute I get the error "Bad
arguments"
If anyone is able to shed some light on the use of RSS in flows, that
would be greatly appreciated.
Thanks,
Alex
