Subject: [PATCH net-next 0/3] ibmvnic: Implement driver-defined queue limits

In this patch series, update the ibmvnic driver to use driver-defined
queue limits instead of limits imposed by the Virtual I/O server
management partition. For some deviced, initial max queue size and
amount limits, despite their definition, can actually be exceeded if
the client driver requests it. With this in mind, define a private
ethtool flag that toggles the use of driver-defined limits. These
limits are currently more than what supported hardware will likely
allow, so the driver will attempt to get as close as possible to
the user request but may not fully succeed.

Thomas Falcon (3):
  ibmvnic: Increase maximum queue size limit
  ibmvnic: Introduce driver limits for ring sizes
  ibmvnic: Add ethtool private flag for driver-defined queue limits
