[Raslan Darawsheh]

Added new capability to the list of rx offloads for hw timestamp

The PMDs how expose this capability will always have it enabled.
But, if the following API got accepted applications can choose
between disable/enable this API.

[PATCH 2/3] app/testpmd: add Rx timestamp in testpmd

[Raslan Darawsheh]

Added new print in case a PMD exposes Rx timestamp.
Also, added a print for timestamp value in rxonly mode
in case the packet was timestamped.

[PATCH 3/3] net/mlx5: add hardware timestamp

[Raslan Darawsheh]

Expose a new capapilty of Rx hw timestamp and
added new device args to enable it hw_timestamp.
It will add the raw hw timestamp into the packets.

Its expected that it will lower down the performance since using it
will disable the cqe comprission, and will add extra checkes in
the vec rx path.

Not sure this comment is accurate, Rx offloads are application request, PMD
does not have to enable it by default.

It is strange to enable/disable this single offload again the application
request.  Why do you need such behavior?

Another point I don't seen any code to retrieve this offloads request from the
port configuration as for the others.  It is expected in the new revision?

I think it should be on top [1] and ideally follow a new offload API without
addition of a new bit field which will be removed soon.

Also, please, update documentation (doc/guides/nics/features.rst)

I agree it should be on top of [1].
Unfortunately since the PMDs will move to the new API only on 18.02, and in the current state Rx offloads are disabled by default, there will be no way to enable this feature without a dedicated bit.

So my suggestion is to keep the timestamp bit on rxmode, and to update the convert function introduced on [1]. This bit will be removed along with the entire bit-field array once the old offloads API will be deprecated.

[PATCH 1/3] ethdev: add Rx HW timestamp capability

this via rte_eth_rxmode.

Hi Raslan,

Is this v4? There are two versions sent today without version
information, it is confusing.

Can you please send latest version again with version information (v4 or
v5) so it will be possible to figure out latest version?

Thanks,
ferruh

Raslan,

Did you make any change in the patches since I acked?
Then, you should remove my 'acked-by' tag and I have to review changes.

Hope you add a cover letter to document changes you make across versions.

Thanks

The code is definitely not rebased on top of a new Rx offload API patch 
which adds
      ignore_offload_bitfield : 1;
exactly in this place.

Hi Andrew,
Did you check Shahaf's email regarding this? Looks like Shahaf suggests keeping it as is for now.

The capability can be reported on both rx_offload_capa and rx_queue_offload_capa. Better to have it:
rx_offload_capa,rx_queue_offload_capa: DEV_RX_OFFLOAD_TIMESTAMP.

Raslan,

It looks like you also rebased it on top of my ARM NEON patch set:
	[PATCH v1 0/7] net/mlx5: add vectorized Rx/Tx burst for ARM

So, it might not be possible for Ferruh to apply on Nelio's patchset, because
filenames are different.

You can either
1) Rebase it on only Nelio's patchset, then I need to add the timestamp code for
ARM NEON to my patch.
2) Rebase it on my patchset with adding the timestamp code for ARM NEON by
yourself.

I'm okay with both ways.

If you choose 1), I ack this patch.

There seems to be one line of change in "app/testpmd: add Rx HW timestamp"

< +                     printf(" - timestamp %lu ", mb->timestamp);
---
> +                     printf(" - timestamp %"PRIu64" ", mb->timestamp);

And we are okay with it.

Thanks,
