The 2 commits are in iproute2-next git repository

Comment 9 Pablo Cascon (Netronome) 2018-12-05 11:27:19 UTC

Is there a time estimate for this, can I help?

Comment 10 Phil Sutter 2018-12-06 18:08:56 UTC

Hi Pablo,

(In reply to Pablo Cascon from comment #9)
> Is there a time estimate for this, can I help?

Time estimate is RHEL7.7 GA, at least for now. Decision has not be made yet whether iproute will be updated in RHEL7.7, so I can't tell for sure. If it does, resolution of this ticket still depends on QE capacity.

Not much you could help with. Of course you could backport the patches, but I don't consider this much work. If you want to get more into maintaining iproute, I could explain once how my workflow looks like. Maybe in a BJ session?

Thanks, Phil

Comment 11 Pablo Cascon (Netronome) 2018-12-07 11:51:41 UTC

Oh I see, not having this in 7.7 would be disappointing. Happy to have Netronome to do external QA for this (have done so for other BZs).

Yeah a workflow session sounds great, I'm in!

Comment 13 John Feeney 2019-03-22 17:11:36 UTC

So is this on the docket for 7.7? It has a devel ack so I am hopeful but the schedule is working against it.

As can be seen above, this is a requirement for a kernel bz from Netronome.

Thank you.

Yes, devel is fine with it. Sadly ticket lacks qa_ack+ for completion.

Jaroslav, please consider granting qa_ack for this ticket.

Comment 16 Pablo Cascon (Netronome) 2019-03-27 10:43:04 UTC

Is there something I can help? Happy to backport the changes proposing patches for the rpm pkg and to test it. Please let me know

Comment 17 Andrea Claudi 2019-03-27 10:46:34 UTC

Hi Pablo, testing is enough, I already backported it. Once someone grants qa_ack+ to this issue I'll take care of the package.

Comment 18 Pablo Cascon (Netronome) 2019-03-27 11:04:04 UTC

Excellent, glad to hear that. Please share a package with the changes in and will test it

Comment 20 Pablo Cascon (Netronome) 2019-05-23 16:46:08 UTC

Thanks for the backport, tested iproute-4.11.0-21.el7 at Netronome and is all good. Would set this BZ to 'Verified' but don't have permissions to do so please consider doing that.
