Hello,
I am trying to test the rte_flow API using the testpmd application. Mainly
I start traffic forwarding, then set a rte_flow rule to drop all traffic,
then check stats to see if traffic is dropped. Tried many different
combinations but traffic is not being dropped.
- Any thoughts on how I can get a drop rule to work using testpmd?
- Also, is there a list of Intel NICs that support rte_flow with
descriptions of what rte_flow features they support?
My NIC is an Intel X710.
My steps:
*(1) Start testpmd:*
$ sudo ./build/app/testpmd –l 12,13,14 –n 4 -- -i

*(4) Set filters to drop all eth traffic from both ports*
testpmd> flow create 0 ingress pattern eth / end actions drop / end
Flow rule #0 created
testpmd> flow create 1 ingress pattern eth / end actions drop / end
Flow rule #0 created
*(5) Check whether traffic is dropped. Traffic is actually not being
dropped, so the filter does not seem to work.*
