[dpdk-dev] [PATCH v3 0/8] 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. 

v3 changes:
 - checkpatch cleanups

v2 changes:
 - added support for keys other than 40 bytes long,
 - now, if RSS key is not set for bonding, it is not set also for slaves,
 - fix - full initial RSS configuration before any slave is added was not
   possible due to the initially zeroed flow_type_rss_offloads for bonding,
 - fix - changed error to warning when slave is synchronizing due to the
   bonding's initial configuration (to allow use slaves' drivers not supporting
   dynamic RSS configuration in bonding), 
 - some code cleanups,
 - updated documentation,
