> The use of a source MAC to direct packets from the VF to the corresponding
> port representor is only ok if there is only one MAC on a VF. To support this
> functionality when the number of MACs on a VF is greater, it is necessary to
> match a source VSI instead of a source MAC.
> 
> Let's use the new switch API that allows matching on metadata.
> 
> If MAC isn't used in match criteria there is no need to handle adding rule
> after virtchnl command. Instead add new rule while port representor is being
> configured.
> 
> Remove rule_added field, checking for sp_rule can be used instead.
> Remove also checking for switchdev running in deleting rule as it can be
> called from unroll context when running flag isn't set. Checking for sp_rule
> covers both context (with and without running flag).
> 
> Rules are added in eswitch configuration flow, so there is no need to have
> replay function.
