Rte_fdir_conf of rte_eth_conf should be initialized before
port initialization.

Hi Rosen,
Why do the fdir_conf must be initialized?
What is the issue you are seeing?
Best,
Ori

Hi Ori,
examples/flow_filtering sample app fails on i40e [1] because i40e requires explicit FDIR configuration.
But rte_flow in and hardware independent ways of describing flow-action, it shouldn't require specific config options for specific hardware.
Is there any chance driver select the FDIR config automatically based on rte_flow rule, unless explicitly a FDIR config set by user?
[1]
Flow can't be created 1 message: Check the mode in fdir_conf.

I don't understand why using rte flow require the use of fdir.
it doesn't make sense to me, that new API will need old one.

I don't know how the i40e driver is implemented but I know
that Mellanox convert the other way around, if fdir is given it is
converted to rte_flow.

It's a good question, I also have this question about Mellanox NIC Driver mlx5_flow.c.
In this file many flow functions call fdir. :)

Firstly, rte_fdir_conf is part of rte_eth_conf definition.
struct rte_eth_conf {
......
struct rte_fdir_conf fdir_conf; /**< FDIR configuration. */
......
};
Secondly, default value of rte_eth_conf.fdir_conf.mode is RTE_FDIR_MODE_NONE, which means Disable FDIR support.
Thirdly, flow_filtering should align with test-pmd, in test-pmd all fdir_conf is initialized.

The only functions that are calling fdir are fdir function,
and you can see that inside of the create function we convert the fdir
Into rte flow.

This sounds to me correct we don't want to enable fdir.
Why should the example app for rte flow use fdir? And align to
testpmd which support everything in in all modes?

In i40e fdir is used to implement filters, that is why rte_flow rules
requires/depends some fdir configurations.
In long term I agree it is better if driver doesn't require any fdir
configuration for rte_flow programing, although not sure if this is completely
possible, cc'ed Qi for more comment.
For short term I am for getting this patch so that sample app can run on i40e
too, and fdir configuration shouldn't effect others. Perhaps it can be good to
add a comment to say why that config option is added and it is a temporary
workaround.

Assuming that the setting for the fdir are fixed for all possible rte_flow rules
I can agree for this workaround but we must add some comment in the code
and also add this comment in the example documentation.
It will be a problem if other PMD will require different default setting.
In this case we must find a better solution.

+1 for commenting code, and as far as I know fdir config only used by Intel PMDs
which we need to confirm all Intel PMDs are OK with change.

Rte_fdir_conf of rte_eth_conf should be initialized before
port initialization. It is a workaround solution when work
with Intel I40e.
Fixes: 4a3ef59a10c8 ("examples/flow_filtering: add simple demo of flow API")

v2 updates:
===========
- Take more test on I40e
- Add comments

Both in the commit log and code comment.

Rte_fdir_conf of rte_eth_conf should be initialized before
port initialization. It is a workaround solution when working
with Intel I40e.
