> Subject: [Intel-wired-lan] [PATCH iwl-next v1 13/15] ice: add VF representors
> one by one
>
> Implement adding representors one by one. Always set switchdev
> environment when first representor is being added and clear environment
> when last one is being removed.
>
> Basic switchdev configuration remains the same. Code related to creating
> and configuring representor was changed.
>
> Instead of setting whole representors in one function handle only one
> representor in setup function. The same with removing representors.
>
> Stop representors when new one is being added or removed. Stop means,
> disabling napi, stopping traffic and removing slow path rule. It is needed
> because ::q_id will change after remapping, so each representor will need
> new rule.
>
> When representor are stopped rebuild control plane VSI with one more or
> one less queue. One more if new representor is being added, one less if
> representor is being removed.
>
> Bridge port is removed during unregister_netdev() call on PR, so there is no
> need to call it from driver side.
>
> After that do remap new queues to correct vector. At the end start all
> representors (napi enable, start queues, add slow path rule).
