From 508d1aa602ef0679a9cfc181ce918fbc4a2b3a45 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Thu, 18 Apr 2013 12:42:58 -0600 Subject: vfio-pci: Use PCI_MSIX_TABLE_BIR, not PCI_MSIX_FLAGS_BIRMASK PCI_MSIX_FLAGS_BIRMASK is mis-named because the BIR mask is in the Table Offset register, not the flags ("Message Control" per spec) register.
