features:

Added support for PCI device NUMA affinity policies. These allow you to
configure how strict your NUMA affinity should be on a per-device basis or,
more specifically, per device alias. These are configured as part of the
``[pci]alias`` configuration option(s).
There are three policies supported:
- ``required`` (must-have)
- ``legacy`` (must-have-if-available) (default)
- ``preferred`` (nice-to-have)
In all cases, strict NUMA affinity is provided if possible. The key
difference between the policies is how much NUMA affinity one is willing to
forsake before failing to schedule.
