I have a ConnectX-7 card for use with a DPDK based 5G UPF. A requirement is RSS on the inner source IP of a GTPU encapsulated packet.
I have been using testpmd(dpdk 25.11) to attempt to configure flow rules to achieve rss e.g.
flow validate 0 ingress pattern eth / ipv4 / udp dst is 2152 / gtp / end actions rss queues 0 1 2 3 end / end
port_flow_complain(): Caught PMD error type 13 (specific pattern item): cause: 0x7fffd2c0fbc8, GTP support is not enabled: Operation not supported
The FLEX_PARSER_PROFILE_ENABLE has been set to 3 , 7 and 8 but the result is the same.
Can anyone advice if the ConnectX-7 can support such RSS configuration or is there something obvious I am missing ?
