svn commit: r248052 - stable/9/sys/dev/pci

[Marius Strobl]

Author: marius
Date: Fri Mar  8 12:57:58 2013
New Revision: 248052
URL: http://svnweb.freebsd.org/changeset/base/248052

Log:
  MFC: r247632
  
  - Complete r231621 (MFC'ed to stable/9 in r232092) by also blacklisting the
    bridge used by VMware for PCIe devices. While at it, update the comment
    now that we know that MSI-X doesn't work with ESXi 5.1 for Intel 82576
    either and the underlying issue is a bug in the MSI-X allocation code of
    the hypervisor.
    Reported by: Harald Schmalzbauer
  - Make the nomatch table const.
