From 6110b1c65ba01d2cce03b6c1640dfe519c6f5884 Mon Sep 17 00:00:00 2001 From: Jerin Jacob Date: Fri, 9 Jun 2017 15:57:46 +0530 Subject: [PATCH] net/thunderx: manage PCI device mapping for SQS VFs Since the commit e84ad157b7bc ("pci: unmap resources if probe fails"), EAL unmaps the PCI device if ethdev probe returns positive or negative value. nicvf thunderx PMD needs special treatment for Secondary queue set(SQS) PCIe VF devices, where, it expects to not unmap or free the memory without registering the ethdev subsystem. Enable the same behavior by using RTE_PCI_DRV_KEEP_MAPPED_RES PCI driver flag.
