Previously in switchdev mode, PF VSI received missed packets, but only ones marked as Rx. Now it is receiving all missed packets. To queue rule per PR isn't needed, because we use PF VSI instead of control VSI now, and it's already correctly configured. Add flag to correctly set LAN_EN bit in default Tx rule. It shouldn't allow packet to go outside when there is a match.
