From 866bc6742c5478023219d5f795d44a0254a3ee88 Mon Sep 17 00:00:00 2001 From: Fiona Trahe Date: Thu, 17 Jan 2019 17:36:23 +0000 Subject: [PATCH] compressdev: add flag to specify where processing is done A new device feature flag, RTE_COMPDEV_FF_OP_DONE_IN_DEQUEUE is added. A PMD should set this if the bulk of the processing is done during the dequeue. It should leave it cleared if the bulk of the processing is done during the enqueue (default). Applications can use this as a hint for tuning.
