Intel E810-CQDA2 fragmented IPv4 RSS question

[mlanzuisi]

Hello,

I need to have some RSS configuration for an Intel E810-CQDA2 (fw 3.20) and dpdk 21.11.

My aim is to send UDP packets (non-fragmented) and fragmented IPv4 packets, having symmetric_toeplitz hash function and a specific RSS key, BOTH DIRECTIONS, on the same queue.

I used the dpdk-testpmd application to make some tests, but what I have is the UDP packets going to the same queue and the IPv4 fragmented packets going to another queue.

Attached you may find a file with 8 packets, 4 UDP and 4 IPv4 fragments, going to 2 different queues.

My dpdk-testpmd settings are:

./dpdk-testpmd -c 0xf -a 0000:37:00.1 -n 4 -- -i --rxq=8 --txq=8 --rxd=384 --txd=384

set fwd rxonly
set verbose 1
port config all rss all
port config 0 rss-hash-key ipv4 6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a
port config 0 rss-hash-key ipv4-frag 6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a
port config 0 rss-hash-key ipv4-udp 6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a6d5a

flow create 0 ingress pattern eth / ipv4 / end actions rss types ipv4 end func symmetric_toeplitz key_len 0 queues end / end
flow create 0 ingress pattern eth / ipv4 / end actions rss types ipv4-frag end func symmetric_toeplitz key_len 0 queues end / end

Anyway, the Intel Premier Support login returns the following error:

What can I do?
