2018-05-31dpdk: Decoupling the meaning of xd->device_index in dpdk_pluginRui Cai1-4/+3
Prior to the change, dpdk plugin assumes xd->device_index is used both as index for internal dpdk_main->devices array and DPDK port index to call into DPDK APIs. However, when running on top of Failsafe PMDs, DPDK port index range may no longer be contiguous (as noted: http://dpdk.org/ml/archives/dev/2018-March/092375.html for related changes in DPDK). Because this, dpdk plugin can no longer iterate through all available DPDK ports with a for 0->rte_eth_dev_count() loop and the assumption of device_index no longer holds. This is part of initial effort to enable vpp running over dpdk on failsafe PMD in Microsoft Azure(3/4).

2018-03-14Prevent calling rte_eth_xstats_get not initialized devSzymon Sliwa1-0/+2
DPDK API forbids calling rte_eth_xstats_get on a port which has not been setup up yet. Citing the DPDK docs (reformated): " The functions exported by the application Ethernet API to setup a device designated by its port identifier must be invoked in the following order: rte_eth_dev_configure() rte_eth_tx_queue_setup() rte_eth_rx_queue_setup() rte_eth_dev_start() Then, the network application can invoke, in any order, the functions exported by the Ethernet API to get the MAC address of a given device, to get the speed and the status of a device physical link, to receive/transmit [burst of] packets, and so on.

2017-04-06Use thread local storage for thread indexDamjan Marion1-4/+4
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
