From 95a896ab861652035920f23ab784cc6f9a7aa521 Mon Sep 17 00:00:00 2001 From: Harry van Haaren Date: Tue, 18 Apr 2017 10:58:40 +0100 Subject: [PATCH] event/sw: fix credit return on invalid queue id This patch returns a credit when an rte_event is enqueued with an invalid queue_id. Previously a credit was leaked from the system. Note that the eventdev instance does not attempt to free any resources that the rte_event owns. As a result, resources owned by the rte_event are leaked. Eg. if the rte_event represents an rte_mbuf, the mbuf will not be freed, and causes a leak from the mempool.
