> Subject: [dpdk-dev] [PATCH v2 0/8] Dynamic RSS Configuration for Bonding
> 
> 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.
> 
> 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,
