Hello,

This is a patchset to do 3 things to improve ibmvnic performance:
    1. Assign affinity hints to ibmvnic queue irq's
    2. Update affinity hints on cpu hotplug events
    3. Introduce transmit packet steering (XPS)

NOTE: If irqbalance is running, you need to stop it from overriding 
  our affinity hints. To do this you can do one of:
   - systemctl stop irqbalance
   - ban the ibmvnic module irqs
      - you must have the latest irqbalance v9.2, the banmod argument was broken before this
      - in /etc/sysconfig/irqbalance -> IRQBALANCE_ARGS="--banmod=ibmvnic"
      - systemctl restart irqbalance

Nick Child (3):
  ibmvnic: Assign IRQ affinity hints to device queues
  ibmvnic: Add hotpluggable CPU callbacks to reassign affinity hints
  ibmvnic: Update XPS assignments during affinity binding
