[dpdk-dev] [PATCHv4 0/9] Dynamic RSS Configuration for Bonding

[Tomasz Kulasek]

OVERVIEW
--------
1) Setting .rxmode.mq_mode for bonding device to ETH_MQ_RX_RSS makes bonding
device fully RSS-capable, so all slaves are synchronized with its configuration.
This mode is intended to provide RSS configuration as known from "dynamic RSS
configuration for one port" and made slaves transparent for client application
implementation.

2) If .rxmode.mq_mode for bonding device isn't ETH_MQ_RX_RSS, slaves are not
synchronized. That provides an ability to configure them manually. This mode may
be useful when application wants to manage RSS in an unusual way and the
consistency of RSS configuration for slaves isn't required.

Turning on/off RSS mode for slaves when bonding is started is not possible.
Other RSS configuration is propagated over slaves, when bonding device API is
used to do it. 

v4 changes:
 - fixed copy-paste error,
 - removed example application as too complex and introducing a new
   dependency,
 - addapted null pmd to be used as testing device for dynamic RSS configuration,
 - addapted test units to use null pmd instead of ring pmd,
 - ring pmd is not used and changed in this patchset,
