Subject: [dpdk-dev] [PATCH v5 3/3] ethdev: fix wrong error return refere to API definition
Date: Fri, 24 Oct 2014 13:58:02 +0800 [thread overview]
Message-ID: <1414130282-17981-4-git-send-email-cunming.liang@intel.com> (raw)
In-Reply-To: <1414130282-17981-1-git-send-email-cunming.liang@intel.com>
Per definition, rte_eth_rx_burst/rte_eth_tx_burst/rte_eth_rx_queue_count returns the packet number.
When RTE_LIBRTE_ETHDEV_DEBUG turns on, retval of FUNC_PTR_OR_ERR_RTE was set to -ENOTSUP.
It makes confusing.
The patch always return 0 no matter no packet or there's error.
Meanwhile set errno in such kind of checking.
