> Subject: [PATCH v2] net/ice/base: fix DCF switch rule
>
> 1. ln_en bit should not be turned on, since we only support Rx VEB.
> 2. lan_en bit need to be turn on for a DCF switch rule, otherwise
> any Tx packet that hit on a rule will be dropped.

> Fixes: fed0c5ca5f19 ("net/ice/base: support programming a new switch
> recipe")
