PCIe congestion events are events generated by the firmware when the
device side has sustained PCIe inbound or outbound traffic above
certain thresholds. The high and low threshold are hysteresis thresholds
to prevent flapping: once the high threshold has been reached, a low

below the low threshold.

What are we supposed to do with a series half of which is tagged for
one tree and half for another? If you want for some of the patches to
go via the shared tree - you have to post them separately.
Ideally you'd post them to the list in a combined "pull request +
patches" format (see for example how Marc posts CAN patches, or Pablo
posts netfilter). Once we pull that you can sent the net-next stuff
separately as patches.

Miscommunication about the proper process, thanks for the explanation.
PR + patches seems cleaner and provides more context,
so I’ll go with that.


I feel like I just had the same exact conversation with Tariq recently.
Really not great when same process explainer has to be given to
multiple people from the same company :( I'd like to remind y'all that
reading the mailing list is not optional:

I do follow the mailing list and double checked what should be done in
this scenario. In the end it's my responsibility so it's my fault.


I think what Mark did here is fine, Yes I understand this is not
applicable to net-next yet, but the point is review and we can do the
following, when review is done:

I can Apply the mlx5-next portion to mlx5-next and Mark on V2 can send the
net-next stuff + A PR request to the mlx5-next branch, this is how we used
to do it all the time, but this time review happens all at once for both
trees.

Jakub is this acceptable ?
