From 339677f87023ccfa8d96b88dd4469a0dc25f813d Mon Sep 17 00:00:00 2001 From: Nikhil Rao Date: Fri, 10 May 2019 13:38:10 +0530 Subject: [PATCH] eventdev: fix Rx adapter event flush MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The Rx adapter flushes events only if it has BATCH_SIZE events buffered where BATCH_SIZE is set to 32, e.g., if a single packet is sent, it is never passed to eventdev. Fix this issue by adding an event buffer flush either when a Rx queue is found to be empty or the adapter service function has processed the max number of packets for an invocation.
