From: Gage Eads Date: Mon, 3 Apr 2017 12:35:50 +0000 (+0530) Subject: eventdev: fix links map initialization for SW PMD X-Git-Tag: spdx-start~3859 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d6c40e22cd65f2c7bd5a9d8a086dc37cf8d85cba;p=dpdk.git eventdev: fix links map initialization for SW PMD This patch initializes the links_map array entries to EVENT_QUEUE_SERVICE_PRIORITY_INVALID, as expected by rte_event_port_links_get(). This is necessary for the sw eventdev PMD, which does not initialize links_map when rte_event_port_setup() calls rte_event_port_unlink().
