From a059a000f81a7251ffed2821f69dd96cfd94c8c7 Mon Sep 17 00:00:00 2001 From: Rui Cai Date: Fri, 11 May 2018 22:55:33 +0000 Subject: dpdk: Decoupling the meaning of xd->device_index in dpdk_plugin 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).
