Hello all,
Ita stumbled upon an issue with rte_flow 'count' and 'mark' actions on
DPDK version 23.11 and higher on Intel ice driver.
By the table at https://doc.dpdk.org/guides/nics/overview.html ice
driver should support these actions.
Specifications:
NIC version: E810-C, 2x100G
Firmware version: 4.7
Kernel Driver: 1.16.3
DDP: 1.3.39.1
DDP Comms 1.3.46.0
DPDK versions that did not accept the rules: 23.11, 24.11
Testpmd start: sudo dpdk-testpmd -a 0000:af:00.1
--log-level=pmd.net.ice.driver:8 --file-prefix=sad -l 0,1 -- --txq=4
--rxq=4 -i --disable-rss
input:
testpmd> flow create 0 ingress pattern eth / ipv4 dst is 159.58.1.0 src
is 195.168.1.0 / end actions count identifier 128 / drop / end
output:
ice_flow_create(): Failed to create flow
port_flow_complain(): Caught PMD error type 16 (specific action): cause:
0x7ffc0c519398, Invalid action type: Invalid argument
input:
testpmd> flow create 0 ingress pattern eth / ipv4 dst is 159.58.1.0 src
is 195.168.1.0 / end actions mark id 2 / drop / end
output:
ice_flow_create(): Failed to create flow
port_flow_complain(): Caught PMD error type 16 (specific action): cause:
0x7fffc6ce9648, Invalid action type: Invalid argument
However, on DPDK version 23.07 both rules are accepted without an issue.
Were these features deprecated? Alternatively, is there any workaround
for counting packets matched against a rule?
Thanks,
Adam.
