RTE_FLOWS rules can be created
------------------------------


With queue action:

testpmd> flow create 0 ingress pattern eth / ipv4 proto is 1  / end actions
queue index 0 / end
ice_flow_create(): Succeeded to create (2) flow
Flow rule #0 created
testpmd> flow create 0 ingress pattern eth / ipv4 / udp src is 22 / end 
actions queue index 0 / end
ice_flow_create(): Succeeded to create (2) flow
Flow rule #1 created

With mark action:

testpmd> flow create 0 ingress pattern eth / ipv4 proto is 1  / end actions
mark id 1 / end
ice_flow_create(): Succeeded to create (2) flow
Flow rule #0 created
testpmd> flow create 0 ingress pattern eth / ipv4 / udp src is 22 / end 
actions mark id 1 / end
ice_flow_create(): Succeeded to create (2) flow
Flow rule #1 created

RTE_FLOWS rules cannot be created

Question
--------

1. Does ice nics support to have several actions ?
2. What is the difference between MARK vs MARK+PASSTRHU ?
   It seems to be the same:
   http://git.dpdk.org/dpdk/commit/?id=0f664f7d57268f9ab9bdef95f0d48b3ce5004a61
   In this case, there is no reason to support MARK and not MARK+PASSTRHU with
2   flows.
