Hi,
Here is a joint work from Mellanox and Napatech, to enable the flow hw
offload with the DPDK generic flow interface (rte_flow).
The basic idea is to associate the flow with a mark id (a unit32_t number).
Later, we then get the flow directly from the mark id, which could bypass
some heavy CPU

Hi,
Here is a joint work from Mellanox and Napatech, to enable the flow hw
offload with the DPDK generic flow interface (rte_flow).

Those checks were part of the miniflow extractor. Moving them out to
act as a general helpers for packet validation.

Subject: RE: [ovs-dev] [PATCH v9 0/7] OVS-DPDK flow offload with rte_flow
Hi Mallesh and Shahaf,
I have tried to reproduce the issue Mallesh is reporting, using
enabling HWOL in a simple phy2phy loopback test.
I wasn’t able to reproduce it, in fact saw big improvement.
Have you tried it? Would really like to address this issue before the v11.

Hi Vishal,
I guess the series is not rebased on top of the HWOL series, many of the
comments are related to this issue.

Just to inform I am taking over this patchset for integration in ovs 2.10

m HW offload for flow mark statistics is
low, because the packet is processed by OVS regardless.
For more advance HWOL like drop action / redirect action it is mandatory.
