++Subject: [PATCH 1/4] Temporary: SR-IOV: Fix VNICs broken filter.
++
++Some blades have VNICs (VFs on a PCI device), which are not
++SR-IOV VFs.
++
++Bug report: "VNICs ignored due to SR-IOV filtering" [1]
++
++HACK: Instead of checking for "physfn", we now rely on testing
++for "physfn/net" subdir to determine whether current eth is
++a SR-IOV VF or something else (thus keeping VNICs).
++
++FIXME: Revert this patch once upstream closes bug [1].

++[ Alexandru Avadanii ]
++Based on Stan's previous patch for ohai, extend fuel-nailgun-agent
++to properly support AArch64 CPUs.
++
++[ Stanislaw Kardach ]
++There is currently little human readable detail in /proc/cpuinfo on
++arm64 so this patch tries to enchance this information by parsing the
++DMI data (using `dmidecode`) and fail gracefully to empty strings
++if no information could not be read from there. By no means this
++parsing is to be taken as a standardised way of discovering an
++arm64 CPU, it is just a suggestion.

+
+Some devices might have removable storage directly on the AArch64
+specific "platform" bus, which is currently filtered-out by
+nailgun-agent.
+
+Allow such devices to be considered as valid storage.
