The optimal values of several transmission & reception related parameters,
such as burst sizes, descriptor ring sizes, and number of queues, varies
between different network interface devices. This patchset allows individual
PMDs to specify their preferred parameter values, and if so indicated by an
application, for them to be used automatically by the ethdev layer.

This RFC/V1 includes per-PMD values for e1000 and i40e but it is expected
that subsequent patchsets will cover other PMDs. A deprecation notice
covering the API/ABI change is in place.

Remy Horton (4):
  ethdev: add support for PMD-tuned Tx/Rx parameters
  net/e1000: add TxRx tuning parameters
  net/i40e: add TxRx tuning parameters
  testpmd: make use of per-PMD TxRx parameters
