Hi Rohith
Thanks for the improvement proposal and writeup.
I wonder if it possible to divide the document by pipeline stage and type
somehow – like receive drops, flow processing drops and
transmit drops.
Flow processing drops due to xlate processing error drops, explicit openflow
drop and resource exhaustion is one division by type.
Maybe also by subtype, such as mbuf depletion for resource exhaustion type, too
deep recursion for xlate error…
It would be good if ‘Internal DP error’ had more specific errors, such as the
above error cases.
Would a table help here based on ‘stage’, ‘type’ and ‘subtype’ somehow; does
not need to be as suggested above ?
Seems you are intending this initially for the userspace datapath ?
If you are maintaining stats on a PMD level as mentioned, did you consider
possibly exporting this into
pmd-stats-show (at least initially), maybe as an option, like verbose or
extended or … ?
You could separate out the implementation details to a
separate later section; maybe some pseudocode or actual code for
implementation discussion part.
Thanks Darrell
