From 00851d47f7be47e45bbc4e502a438921642cd965 Mon Sep 17 00:00:00 2001 From: Reshma Pattan Date: Wed, 15 Jun 2016 15:06:20 +0100 Subject: [PATCH] ethdev: get queues numbers The new fields nb_rx_queues and nb_tx_queues are added to the rte_eth_dev_info structure. Changes to API rte_eth_dev_info_get() are done to update these new fields to the rte_eth_dev_info object. Release notes is updated with the changes. The librte_pdump library needs to register Rx and Tx callbacks for all the nb_rx_queues and nb_tx_queues, when application wants to capture the packets on all the software configured number of Rx and Tx queues of the device. So far there is no support to get nb_rx_queues and nb_tx_queues information from the ethdev library. Hence these changes are introduced.
