From 4d18760c67af2688a6f9d3f0131dc505e0b9f2c9 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Wed, 17 Apr 2013 18:10:07 -0600 Subject: [PATCH] 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.
