Subject: [dpdk-dev] [PATCH] 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")
