Hi Ido,

The 800 Series DDP for the GTPoGRE package is available only to CNDA customers.

Thanks,
Sandeep

Hi

Does E810 support RSS for 2 tunnels GRE/GTP based on the inner addresses?

Test docs say it should
https://doc.dpdk.org/dts/test_plans/ice_advanced_iavf_rss_gtpogre_test_plan.html
https://mails.dpdk.org/archives/dts/2021-August/013814.html

But I cannot make it work.
I cannot find the mentioned ice_gtp-o-gre-1.3.5.0.pkg
I'm using the latest ice_comms-1.3.61.0.pkg

    ICE_INIT: ice_load_pkg_type(): Active package is: 1.3.61.0, ICE COMMS Package (double VLAN mode)

It does work for GTP only (w/o GRE) with this fdir rule

    testpmd> flow create 0 ingress pattern eth / ipv4 / udp / gtpu  / ipv4 / end actions rss types ipv4 end queues end / end
    Flow rule #0 created

But it does NOT work for GTPoGRE traffic. I also fail to add GRE specific rule as appear in the docs.
Seems like 'gre' is an invalid input pattern
    
    testpmd> flow create 0 ingress pattern eth / ipv4 / gre / ipv4 / udp / gtpu  / ipv4 / end actions rss types ipv4 end queues end / end
    ICE_DRIVER: ice_flow_create(): Failed to create flow
    port_flow_complain(): Caught PMD error type 2 (flow rule (handle)): Invalid input pattern: Invalid argument
    
Should it work? Do I miss something?

Thanx
Ido
