New Revision: 248053
URL: http://svnweb.freebsd.org/changeset/base/248053
Log:
- Complete r231621 (MFC'ed to stable/8 in r232093) 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.
