I think in the past threshold has been mentioned as "significant contribution",
although this is kind of vague, it sounds lighter than "complete rewrite",
anyway I agree for this patch it looks overkill to claim the copyright.

That's a quite clear threshold definition, and my modifications clearly don't fall into this category.

Most projects including DPDK do not add additional copyrights unless it
is a complete rewrite. Please don't clutter the code with this stuff.

Hi Olivier,

Thank you for responding to this, and sorry about the noise with my initial failed commit attempts.

I also added the two ECN flags and descriptions of all the flags. And removed the misleading ALL flag.

I don't know the formal or customary threshold criteria for adding a copyright notice, so I just added it. It's our first direct contribution where we didn't just send the corrections to another contributor, so I thought it would be nice to have our name in here. You're the maintainer, so I'll leave the final decision up to you.

Agreed. I assume someone more git-experienced than myself can take care of this.

Moving these flags in rte_tcp.h makes sense.

But I think they will need to be renamed with a RTE_ prefix inside this
patchset: https://patches.dpdk.org/patch/52556/
So we need to take care to the dependency between these 2 patchsets.

[dpdk-dev] [PATCH] librte_net: define TCP flags in rte_tcp.h instead of in rte_eth_ctrl.h

[Morten Brørup]

TCP flags were moved to the TCP header file from the Ethernet control
header file, keeping their names intact.

Missing TCP ECN flags were added.

The ALL mask did not include TCP ECN flags, so it was renamed to reflect
that it applies to N-tuple filtering only.
A driver using the ALL mask was updated accordingly.

[dpdk-dev] [PATCH] librte_net: define TCP flags in rte_tcp.h instead of in rte_eth_ctrl.h

[Morten Brørup]

TCP flags were moved to the TCP header file from the Ethernet control
header file, keeping their names intact.

Missing TCP ECN flags were added.

The ALL mask did not include TCP ECN flags, so it was renamed to reflect
that it applies to N-tuple filtering only.
A driver using the ALL mask was updated accordingly.

[dpdk-dev] [PATCH] librte_net: define TCP flags in rte_tcp.h instead of in rte_eth_ctrl.h

[Morten Brørup]

TCP flags were moved to the TCP header file from the Ethernet control
header file, keeping their names intact.

Missing TCP ECN flags were added.

The ALL mask did not include TCP ECN flags, so it was renamed to
reflect that it applies to N-tuple filtering only.

A driver using the ALL mask was updated accordingly.
