From ea629d873f3e140fb2e3181c30413e485ee9002b Mon Sep 17 00:00:00 2001 From: Yongji Xie Date: Wed, 15 Feb 2017 14:50:22 +0800 Subject: [PATCH] PCI: Ignore requested alignment for IOV BARs We would call pci_reassigndev_resource_alignment() before pci_init_capabilities(). So the requested alignment would never work for IOV BARs. Furthermore, it's meaningless to request additional alignment for IOV BARs, the IOV BAR alignment is only determined by the VF BAR size.
