flow group.
- Flow metering, including meter policy API.
- Flow integrity offload API.

Limitations
-----------
or
flow create 0 ingress pattern integrity level is 0 value mask l4_ok value spec 0 / eth / ipv4 proto is udp / end …
+- Connection tracking:
+
+ - Cannot co-exist with ASO meter, ASO age action in a single flow rule.
+ - Flow rules insertion rate and memory consumption need more optimization.
+ - 256 ports maximum.
+ - 4M connections maximum.

+Sub-Function representor
+------------------------
+
+Sub-Function is a portion of the PCI device, a SF netdev has its own
dedicated queues(txq, rxq). A SF netdev supports E-Switch representation
offload similar to existing PF and VF representors. A SF shares PCI
level resources with other SFs and/or with its parent PCI function.
for better performance. For VMs, verify that the right CPU
and NUMA node are pinned according to the above. Run::
- lstopo-no-graphics
+ lstopo-no-graphics --merge
to identify the NUMA node to which the PCIe adapter is connected.
