[dpdk-dev] [PATCH 0/3] null driver improvements for testability

[Paul Atkins <patkins@brocade.com>]

This patchset adds functionality to the null driver help when testing
a dataplane that uses dpdk.  The idea is that the the dataplane can
have multiple null interfaces attached, and each of theses can be
assigned a mac address. Packets can then be injected into the null
drivers by adding them to a ring, giving the application complete
control of the packets that arrive.  Packets that are sent by a null
driver can be stored on a ring, where the application can pick them up
and verify it is what was expected.  To allow the application to know
when packets have been pulled of the rx ring, counters of the number of
times an rx poll has been made are kept, and these can be retrieved via
the existing APIs.

All of these enhancements are using the existing APIs, and do not
modify the existing behaviour of the null driver if these features
are not configured.


Paul Atkins (3):
  null: add a new arg to allow users to specify ether address
  null: add rings to allow user to provide the mbufs for rx/tx
  null: add xstats to provide the number of rx polls
